Hello everyone.  I am modelling the Union Pacific's current excursion train consist pulled by FEF-3 4-8-4 Northern #844.  The consist calls for an auxiliary water tender, 60 foot double plugdoor express boxcar, and a track inspection car.  I know Bachmann sells auxiliary water tenders, but not for Union Pacific.  Anyone have any ideas on how to get my hands on one of these tenders, as well as the other cars mentioned?
