I bought one of these old kato passanger coaches at my local 2nd hand shop. Was quite wondering what would be the leading train( or train set ) for this?. Was aiming for a C11 setup but I can't find any historical photos with the blue coaches. I mainly do showa era SLs. If it were electric locomotives, does EF65, and EF66 an appropriate choice?. Sure do hope if i could find some brown old coaches too, this would be much more fun, and also some mail/parcel coaches.
