Les,
Your right--it boils down to money, but I do think that there will be a time on the C&TS when the K-36's will need some extensive repairs like the 489 is going through now. How long has the 487 been in continuous service--seems like forever. If they get a couple of the 37's in the rotation it would help keep a stable fleet and allow the railroad not to be sidelined or have to curtail service due to motive power shortages. I remember only a couple years ago when they only had I think one operating locomotive on the C&TS!!!!!
