I know this doesn’t help but the two that Revelstoke Limited LLC converted to Luxury Locomotive Lodge's are an insult if you ask me!, what a waste! Montana rail link which acquired some in 1993 have sold theirs displaced by the SD70ace's and according to LocoPhoto's forum their are no more in regular service and I think Utah Railway's f45's have been sold to NRE I also know that the ones Montana had were equipped with the Wabtec QES1000's.
sorry I could'nt be anymore help
GE JUST DON'T MAKE TOASTERS YA KNOW!
