Electrical equipment order confirmed


The Trust has agreed a £350,000 order for a state-of-the-art electrical system for No. 2007 Prince of Wales. The electrical system, based on that fitted to No. 60163 Tornado, includes systems that generate and store electricity, together with lighting and instrumentation systems. Also included are all current railway safety and communication systems, plus new systems that will soon be needed on the Network Rail main line.

In order to complete No. 2007 Prince of Wales by 2021, the Trust needed start work on the electrical systems during the third quarter of 2018 and at its most recent board meeting, the Trustees reviewed the proposed system’s architecture, key equipment locations, wiring & interconnect, power generation & supply, essential lamps, systems and instrumentation.

The Electrical system for No. 2007 Prince of Wales will be based on that fitted to No. 60163 Tornado which has operated successfully for the past 10 years. It will be based on the following key principles:

  • Dual redundant power supplies
  • Electronic battery management
  • Steam turbine and axle-driven generators
  • All LED lighting
  • Structured trunking system for wiring
  • Military specification components for reliability
  • Optimised equipment locations for minimum wiring

The new system will improve on that fitted to Tornado, especially with regard to access and maintenance, and systems will be moved from the engine to the tender where practical. It will use the same tried and tested components for critical systems (including Huber + Suhner 4GKW Traction Cable for all wiring and AB MIL-C 5015 bayonet connectors). Conventional wiring will be used for power and lighting. A bus-based communication system is being considered for instrumentation, along with wireless connectivity where required.

The key elements include:

  • Electrical systems: battery boxes (under the cab), control panels (driver’s & fireman’s side roof), distribution boards (under the crew seats), steam turbo-generators (two located on fireman’s side running plate, (arranged to look like the feedwater heater on the original class P2 No. 2001 Cock O’The North) and tender alternator (behind and driven from the rear axle)
  • Existing railway safety systems: On-Train Monitoring Recorder (OTMR), Train Protection & Warning System (TPWS) and Global System for Mobile Communications Railway (GSM-R)
  • European Train Control System (ETCS): European Vital Computer (EVC), Train Interface Unit (TIU), Juridical Recording Unit (JRU), Euroradio, Balise Transmission Module (BTM) and ETCS Batteries (if required) all in a new locker on front of tender with a filtered air supply for cooling; Balise Antenna (under engine); 2-3 Tachometers; 1-2 Doppler Radars; two GSM-R Data Radio Antennas (on rear of tender top); and Driver Machine Interface (DMI)
  • Wiring system: a structured stainless steel box trunking system, designed on 3D CAD, will be used for the main ‘spine’ trunks on engine and tender; most of the rest of the conduit will be flexible; visible conduit (e.g. in the cab) will be galvanised tube; an improved system for connecting the cab to the frames will be implemented
  • Power generation: a new design for an axle-driven alternator based on an off-the-shelf truck alternator is well underway (output around 160A at 27V DC (4.3KVA); the Trust’s own design of turbo-generator also underway (output around 25A at 27V DC (675VA) with two fitted with a £7,350 order for a first complete new turbine wheel placed with Durham Precision Engineering; there will also be a shore power supply fitted
  • Essential lamps: replicas of the distinctive class P2 lamps will be constructed and fitted with new LED luminaries inside (the P2s didn’t have Stones marker lamps, so will need a combined head, tail and marker lamp within the same housing); the rear of the tender will be equipped with recessed marker/tail lamps and lamp brackets/plugin points for headlamps if needed on heritage railways (or for a main line Plandampf)
  • Instrumentation system: drawbar horsepower measurement (effectively a dynamometer car), cameras, pressure sensors, temperature monitors and sensors to monitor important cambox parameters

The team, led by Electrical Director Rob Morland, includes Alan Parkin (power generation and 3D CAD design), John Moyce (instrumentation), Steve Sims (instrumentation) and Paul Depledge (implementation). The electrical part of the project will run from now through to 2021, in parallel with the mechanical engineering work.

Rob Morland, Electricals Director and Trustee, The A1 Steam Locomotive Trust, commented, “The electrical system for No. 2007 Prince of Wales build upon that which has successfully operated on No. 60163 Tornado for the past 10 years. In that time there have only been a few minor component failures, and some water ingress issues, in a system which has over three miles of cable, 60 connectors and 250 separate wire runs. The new system will benefit from the experience of operating Tornado on the main line and heritage railways, particularly with regards to access and maintenance. It is also, as much as possible, future-proofed to enable Prince of Wales to operate seamlessly on the modern and future Digital Railway.”

Mark Allatt, P2 Project Director and Trustee, The A1 Steam Locomotive Trust, added, “We are delighted with the level of support that the project to build Britain’s most powerful steam locomotive has received since its launch. Thanks to our supporters’ continued generosity, over £3m has now been donated or pledged.

“Our £350,000 investment in Prince of Wales’s electrical system is part of the Trust’s policy of enabling our new steam locomotives to work on the modern railway side-by-side with the latest diesel and electric traction. Although the initial investment will come from our general construction funds, we will be launching a dedicated funding campaign in due course. We remain confident that we are on-track for completion of new Gresley class P2 locomotive No. 2007 Prince of Wales in 2021.

A birthday party surprise!

Unfortunately Tornado was unable to attend her 10th birthday party in Darlington but it looks like Prince of Wales had a surprise waiting for the guests!  Again, many thanks to all those who signed up to The Mikado Club to get No. 2007 on her wheels.

The Motion Club passes the 1/3rd mark

Motion fund for Britain’s most powerful steam locomotive reaches almost £75,000 and the order for the heavy motion is placed.

We are pleased to announce that The Motion Club, which was launched in April 2018, has welcomed over a third of its 175-member target, with 60 people already signed up. The Motion Club aims to raise £210,000, through 175 supporters each donating £1,000 (plus Gift Aid) in up to eight payments of £125, to manufacture the motion for No. 2007 Prince of Wales.

In order to complete No. 2007 by 2021, we needed to order the heavy motion this year. Thanks to the generosity of our supporters and the quick uptake of The Motion Club, we were confident enough to order the motion. The £181,000 order has been placed with Stephenson Engineering Ltd of Atherton, Manchester for the heavy motion. The order includes the forging, machining and heat treatment of the nine heavy motion rods – intermediate coupling rod LH/RH, trailing coupling rod LH/RH, leading coupling rod LH/RH, outside connecting rod LH/RH and the inside connecting rod assembly (including strap, gluts and strap nuts and washers) – and the combined piston and rod. The motion is expected to be delivered in batches between December 2018 and December 2019, with the first item, the intermediate coupling rods, expected to be delivered towards the end of December 2018. Orders to follow for the motion include rod bushes, oil box covers and miscellaneous components.

Mark Allatt, P2 Project Director and Trustee, The A1 Steam Locomotive Trust, commented, “We are delighted with the level of support that the project to build Britain’s most powerful steam locomotive has received since its launch. Thanks to our supporters’ continued generosity, over £3m has now been donated or pledged. Recently we have been focused on preparing to wheel No. 2007 and completing the boiler cladding.

“We now want to turn our attention to the motion which is our next major design and manufacturing challenge. Given the level of support The Motion Club has received in just three months, we are confident we can raise the additional £135,000 needed to pay for the heavy motion, and remain on-track for completion of new Gresley class P2 locomotive, No. 2007 Prince of Wales in 2021.

“I would encourage all steam enthusiasts who haven’t yet contributed to this exciting project to help us to meet these deadlines by becoming a member of The Motion Club or a monthly ‘P2 for the price of a pint of beer a week’ Covenantor. It’s time to get on board! This year will see further major announcements as the construction of new Gresley class P2 No. 2007 Prince of Wales gathers pace.”

A ‘tyring’ day!

Excellent progress continues to be made with the process of wheeling and tyring at South Devon Railway (Engineering).  These photos show the steps involved in preparing the wheel centres (now all fitted to their axles) for the tyres to be shrunk on.  Assembling Tornado’s wheels used numerous contractors and multiple road miles so, for the Trust, having a ‘one stop shop’ that could do all the work has saved a lot of haulage and time.  All photos by David Elliott.

Boiler tender issued


The Trust is seeking expressions of interest in the manufacture of No. 2007’s boiler. The boiler for Prince of Wales will be similar to that which was built by DB Dampflokwerk Meiningen, Germany for new Peppercorn A1 class No. 60163 Tornado in 2006/7, being a fully welded design with a steel firebox. The A1 Steam Locomotive Trust owns the design rights to the boiler and it is intended that a number of minor modifications that have been applied to Tornado’s boiler since it was originally built will be incorporated into this design. The Trust has already sent the arrangement drawing to ten potential manufacturers in the UK and overseas but is still open to approaches by other interested parties.

The boiler for the new class P2 locomotive is intended to be directly interchangeable with the diagram 118A boiler fitted to Tornado and the constructor of the new boiler should be able to demonstrate fulfilment of the following requirements:

  1. To have a track record in construction of new boilers and/or major repairs to existing boilers of a similar size as the boiler of the new Gresley class P2.
  2. To have facilities and equipment large enough to adequately handle a boiler of this size.
  3. To operate a quality management system (QMS), which shall as a minimum include ISO 9000 and which clearly demonstrates adequate control of critical processes including material specification and traceability, weld procedures and welder qualifications.
  4. Have a clear relationship with a mutually agreed notified body to facilitate certification of the boiler to the appropriate National and European Standards.
  5. Ability to deliver on time to an agreed schedule.

The Trust has requested that potential suppliers provide an indicative price for a boiler to the standard defined in the drawings supplied. The anticipated schedule is:

  • Selection of supplier end 2018
  • Negotiations and finalisation of technical specification quarters one and two 2019
  • Firm order placed June 2019
  • Delivery required January 2021

No. 2007’s boiler in detail:

  • Use of diagram 118A Tornado boiler with detailed modifications to improve overhaul life
  • Interchangeable with Tornado boiler
  • Tornado boiler is 17in shorter than P2 boiler – No. 2007’s smoke box has been extended within the cladding
  • 250psi of No. 60163’s boiler will be retained to improve economy and increase maximum power

Following the success of The Founders Club, which was designed to get to the P2 Project to the point of cutting No. 2007’s frames, the Trust decided to establish The Boiler Club to fund the construction of Prince of Wales’s boiler. The Trust set an initial target for The Founders Club of at least £100,000 from 100 ‘Founders’ but due to the overwhelming generosity of its supporters actually raised £450,000 (including gift aid) from over 360 donors. It is the Trust’s desire to leave No. 2007 Prince of Wales debt free upon completion and therefore its aim is to raise at least £600,000 for The Boiler Club from 300 supporters each donating £2,000 to the project (in up to 40 payments of £50 by standing order). In return for this commitment, members of The Boiler Club receive these special benefits:

  • Opportunity to buy ticket (seat already reserved) on No. 2007’s first main line train
  • Reasonable access to No. 2007 at all times
  • Opportunity to buy exclusive Boiler Club badge
  • Opportunity to join one of the teams building No. 2007
  • First choice of other components to sponsor
  • Special limited edition version (signed/numbered) of the first official painting of No. 2007 Prince of Wales with No. 60163 Tornado –‘Dream Team’ by renowned railway artist Chris Ludlow
  • Special Boiler Club day with Tornado.

 The Trust is delighted that over half of the required 300 members have joined The Boiler Club fundraising campaign. Launched in October 2014 to raise the £600,000 needed pay for the manufacture of the boiler, The Boiler Club now has almost 160 members who have each donated or pledged £2,000 (plus Gift Aid) meaning almost £400,000 (including Gift Aid) has been pledged so far for the boiler.  You can join The Boiler Club here.

Mark Allatt, Trustee and P2 Project Director, The A1 Steam Locomotive Trust, commented, “The boiler is the beating heart of a steam locomotive and to keep the construction of No. 2007 Prince of Wales on schedule for completion in 2021 we need to place the order for the boiler in 2019 for delivery in 2021.

“Passing the half-way point in the membership of The Boiler Club marks a significant milestone in the project to build Britain’s most powerful steam locomotive. It is our desire if possible to complete No. 2007 debt-free and so we launched The Boiler Club in October 2014 to raise £600,000 to fund Prince of Wales’s boiler.

“With this latest announcement, no-one can now doubt that we really mean business. The next few months will see further major announcements as the construction of the locomotive gathers pace. We are now appealing to those who want to be a part of this exciting project to become Covenantors, sponsors and volunteers to help us maintain this momentum.”
