I’ve always liked bubble cars (let’s be honest, who doesn’t?) and i recently stumbled across a cheap Lima class 121 so Brettell Road will get a class 122 to play with.  Here it is ready for paint.

The roof has had the grooves filled (not sure why lima did this when the retooled the 117 as the roof was the only bit of that model they got right ) with new vents from MJT.  The cab domes are spares from the DC Kits 304 kit with my own etched fronts.  The exhausts are spares from Dapol (with thanks to Geoff of Western Thunder for pointing out they were available as spares.) and the headcode boxes are microstrip.  Buffers are from 51L and the bogies are Hornby class 110 as per most of my DMU’s. Buffer steps are my own etch and the underframe had has some strategic holes drilled in it to open it up a bit.
