Hi Richie, sounds a good project, Heljan 86's do appear a bit thin on the ground, however Hornby 86 are always around and scrub up well with flush glazing and a change of pantograph, and twin power bogies, Shawplan make a good screen etch for the Lima 87, and depending on your ambitions look better with Hornby class 90 bogies , or cut down a 90 chasis for the 87 body .
