Motive power replacement

The FA2 chassis from the Life-Like Proto 2000 range has near-correct bogie centres (101.6 mm instead of 99.8 mm). The bogies on this chassis may not clear the front bufferbeam valances and you may have to use Athearn GP9 bogies instead. To fit the Proto 2000 chassis correctly, you should narrow the inside measurement of the loco body shell to 29 mm. Other modifications to the original parts may also be necessary.

Check current availability of the Life-Like chassis with Model Junction.
