135 is a GP60M diesel engine being built by EMD. 135 was originally built for the Santa Fe in July, 1990, but it didn't work for the Santa Fe for long because five years later Santa Fe merged with Burlington Northern to be BNSF. 135 is still in service today. There are plans to try and set 135 aside for preservation in Topeka, KS where it would be restored to Santa Fe warbonnet.
