I have started to pick up some French tinplate. I have long wanted an Orient Express train. The version I knew about - MTH - required more than my layout could handle. Then I discovered French tinplate - specifically French Hornby and JEP.
This is the French Hornby BB8051 and several CIWL cars.
This is the larger BB9200 series locomotive.
JEP made the BB8100 series locomotive and CIWL cars.
While I am personally partial to electric locomotives, both French Hornby and JEP made steamers. This is a JEP.
I believe all of these locomotives and cars were made in the 1950's and 1960's. Several of the smaller units will run on AC or DC. The BB9201 and BB8101 require 3-rail DC.
