Although they are a world apart from what I'm actually modelling,I do find british prototype based models very nice and would like to add one or two to my roster.I have my mind set on a pair of Graham Farish models that I find particularly nice but am a bit hesitant as I don't know anything about these products.How good are they?Are they DCC ready or at least reasonably convertible?Do they feature regular couplers,either Rapidos or MT compatible types?Wheel flanges...do they need code 80 track?I suppose they do follow model train standards but would like to be sure.Being offered by Bachmann who are known for uneven quality,I'm wondering if....Any comment would be appreciated,thanks.
