First Bachmann 4-Cep conversion.

April 11, 2017

The Bachmann 4-Cep in original condition as supplied out of the box. A conversion is more of a long project than anything of extreme complexity. Until you have to repaint it!

A long overdue project for my EM gauge Folkestone East project is to convert several OO gauge Bachmann Class 411 4-Cep units to represent the Swindon refurbished units; work undertaken to upgrade the fleet in the early 1980s. The model, as it is supplied, is a four-car set in original ‘as built’ condition with typical Mark 1 coach features. The refurbished 4-Cep conversion involves a long-winded removal of the glazing units and moulded window frames; relocating the guards compartments to the CK and fitting of new glazing units and hopper window frames. The moulded window frames were pared away and smoothed down ready for the new etched ones which are fitted once all painting is complete. The stainless steel colour will be a good representation of the unpainted bare metal of those fitted to refurbished 4-Ceps. This was done using a stainless steel etch designed by another Southern Region modeller called David Crow (see below) and kindly made freely available.

The guards compartment was relocated to a middle trailer during refurbishment work. The original guards compartments in the outer DMBSO vehicles was removed to provide an additional seating bay.

The conversion will involve several other detail changes including swapping the bogies for Commonwealth types and double checking the type of roof ventilator fitted to your chosen unit – they did vary with ridge dome, scallop dome and shell vents all featuring in the 4-Cep fleet. I started work by converting the corridor composite trailer into a composite brake – the two guards compartments in the outer DMBSO trailers being located to bring the 4-Ceps in line with other express stock such as the 4-Cig, 4-Big and 4-Vep units.

Filing plastic away to fit the etched overlay section flush with the rest of the coach sides.

With the guards compartment relocated, the DMBSOs are converted to remove the guards compartments from those vehicles and cut in new windows for an additional seating bay. The etched window frames are used as a guide.

Once positioned as near as can be, the window in the original double doors is sealed up and the new windows cut in on both sides of the trailer.

The door line, door handle and hinges are removed too to create a smooth surface. Some filling is required to complete this work.

A final rub down in the kitchen sink with fine wet and dry paper and the model is ready for the paint shop – models rarely look well after this much work. The first coat of paint will quickly reveal flaws in the body work that need further attention. Rub down again, fill where necessary and re-coat before progressing to more complex parts of the livery! This model is to become No. 1562 finished in Network South-East livery (see below). The full size unit survived until around 2004.
