Western Train Czo. Is now offering C.P. Huntington Train conversions. They will convert your existing C.P. Huntington Engine to a cleaner burning, more efficient diesel drive system. They will remove your train’s old transmissions, transfer cases, drive shafts, and overheating engines and replace it with a diesel engine built to last. Western Train’s Hydrostatic Diesel conversions will renew your train ride without paying the cost of a new engine.
