I buy for prototype model and roadname....steam locos, 99%, except for gas electrics and other rail cars. Very little spent over last few years, due to lack of availability. They make it, l will come. Roadnames l regard as overcommon in three rail production, l won't buy cars, either. Will buy cars for obscure historical roads to run, from west and midwest, examples might be C&IM, C&EI, Mich. UP copper roads, etc.
