Does anyone know the history of RFRX 4203 and 4205? They are currently owned by CN. They acquired them when the bought the Savage Alberta Railway (formerly Alberta Railnet) recently.

4203, GE #41913 4/78 ex-BNSF 4203, exx-MNCW 804, nee-MNCR 1906, exxx-CR 1906. Sold to RFCX 12/99, used on Port of Tillamook Bay and Portland & Western, sold to Savage Alberta 6/06.

4205, GE #41915 4/78 ex-BNSF 4205, exx-MNCW 806, nee-MNCR 1908, exxx-CR 1908. Same info as 4203.

MNCR & MNCW both reporting marks for Metro-North Commuter Railroad, MNCR for equipment used in revenue service, MNCW non-revenue.
