Potential Project Relocation to Whitwell and Reepham Station, Norfolk.

Preliminary talks have commenced with the Trustees of Whitwell and Reepham Station, Norfolk regarding the future relocation of GER 789. Such a move is necessitated as Tyseley Steam Locomotive Works is unable to accommodate 789’s frames upon their assembly.

Whitwell and Reepham Station will provide GER 789 with excellent opportunities to further progress via engineering, publicity and public accessibility.

Engineering Update 3rd October 2017

Negotiations are ongoing to identify a suitable home for our soon to be assembled frames, smokebox, chimney and bunker. A significant “news update” is expected to be published soon.

Engineering News September 2017

Elliot Powick has CAD designed the bracketry that is necessary for the assembly of GER 789’s frames. Tyseley is to inspect and approve the final designs prior to fabrication.

With assembly of the frames imminent, attention is focused on relocating from Tyseley to another site. Discussions have been held with a potential display partner and an official announcement will be made soon.

The GER 789 display will consist of assembled frames mounted on bespoke frame supports. The smokebox complete with a prosthetic chimney will be attached to the cylinder block with the bunker attached to the rear with replica GER 789  plates affixed to the bunker sides.

HRA Award

Today the team (Chairman Steve Cooper, trustees Bob Ayton, Aidan Kelly and Greg Kiteos) visited the Epping Ongar Railway to meet Ian Leigh, Finance Director from The Heritage Railway Association and we were presented with an HRA award for Broadcast and Social Media.  This was the culmination of hard work to increase our profile through the website and social media.   Thanks goes to Dean Walton and The Epping Ongar Railway for their hospitality.   Also thanks to Andy Butler who couldn’t make today but along with Greg have been busy organising events for Holden to attend.

Stafford Road Design Ltd (Elliot Powick) has progressed the Stephenson’s valve motion CAD models for GER 789. This was a particularly challenging task as the original drawings were not available to the Trust (presumed lost or destroyed,) therefore a vast amount of detailed work has been undertaken by Stafford Road Design for which the Trust is extremely grateful.  View animations by clicking on each individual thumbnail.

The Trusts’ Chief Mechanical Engineer Elliot Powick has recenltly identified the correct design of motion bracket for GER 789 from four posible options. The resultant CAD model has been used by Premier Patterns and Castings Ltd to manufacture a polymer pattern that will shortly be sent to a foundry in readiness for casting of the motion bracket.

June 2017 Engineering Report

Following a meeting with Bob Meanley at Tyseley on May 19th it has become apparent that, with Tyseley Loco Works (TLW) current work load, the current plan for frame erection would be difficult to implement.

The original plan was for TLW to procure all the peripheral components things like gussets, rivets, bolts etc and the F5 Trust were left to provide any outstanding castings (motion bracket etc). At the moment, what with TLW’s current work load the current schedule was not going to be achievable mainly down to other current TLW projects unexpectedly over-running (anyone that’s been involved with loco restoration will wholly understand) so it was decided that another proactive way to get the frames built was needed.

The plan now is a quick 1-2 week assembly turn around in which the F5 Trust with TLW’s assistance will procure everything required to put the frames together and will be project managed so that all the parts come together for their allotted time in TLW’s workshop.

This in turn means that all the additional parts will need to be acquired in readiness for this to begin. So that’s 184 rivets,  113 bolts, 129 nuts, 12 brackets, 1 extra machined casting, machined frames and buffer beams all to hit TLW’s workshops at the same point then 2 weeks later we should have a nice new set of erected frames.

Machined Motion Bracket

The last main casting required is the motion bracket. Now the Trust has ascertained which bracket it required we can now move forward and make the pattern, cast and machine. This is one of the last pieces needed and will be cast, machined and delivered just prior to the frame erection.

Modifications

The Trust is currently looking at alternative options to some of the cast brackets required for frame erection. With current welding techniques it should be possible to create the same parts using laser cut parts welded together to form a copy of the cast bracket at a considerable cost reduction compared to patterns, castings and machining. This process has been used before on other loco restorations so it should be relatively easy to do so. We’re currently in conversation with a few fabrication companies who can assist with these parts and possibly sponsorship of some if not all of the costs.
