The tricky business of converting old Graham Farish Mark 2 coaches into a Class 310 EMU has reached the testing stage. The model is being built using Electra Railway Graphics self-adhesive overlays onto heavily modified clear-sided Mark 2 coach bodies. The result, I hope, will be a respectable representation of a 3-car Regional Railways Class 310/1 (No. 310106) which was a common sight in the West Midlands at one time and a signature model for the layout.
The conversion is not the easiest one I have done in N gauge so far – the 3D printed cabs being far from satisfactory and having a distinctly grainy texture to them which is not simple to remove. In fact, the printed material is so hard, wet and dry paper struggled to smooth the grittiness down to any degree. On reflection, scratch building from styrene card may have produced a better result. Weeks after completing the main part of the conversion, the unit is finally being tested on the layout with bar couplings and new gangways designed to close up the gap between the coaches. As you can see, I was far from happy with the join between the cab roof and the main roof moulding. Considerably more finishing work (and patience) was put into making this area of the model as satisfactory as possible together with a final coat of dark grey paint for the roof.
Having filed the cab ends to more or less the right shape, re-profiled the cab windows and removed the bowed ends from the Mark 2 coach body moulding, replacing them with a flat suburban stock end with the gangway extension unique to Class 310 and Class 312 EMUs, the model was relatively simple to finish with the vinyl sides. The centre coach has pantograph well cut in it, fitted with insulators cut from 10BA brass screws and a Dapol ‘pan’. Cab painting was made awkward by the coarse printed texture, making smooth clean lines difficult to achieve.
The model will be more or less complete for an outing to the Falkirk exhibition this weekend, together with the Class 90 I have been working on recently. No. 90 033 requires a little more finishing to the roof, pantograph well and to disguise that Digitrax DZ126 decoder which can be seen through the cab windows! Despite the challenges and sometimes frustrations of working on older N gauge models, both are a welcome additions to the 25kV fleet. A Class 323 is the next EMU project – also a signature EMU for the West Midlands area.
The Falkirk exhibition is the last major show in the Scottish exhibition circuit calendar and is held annually at the Forth Valley College in Grangemouth Road, Falkirk, FK2 9AD. It’s usually quite an event; much more laid back than a certain other model railway show being staged this weekend at the NEC and a lot of fun.
