lately i've been wondering why the Union Pacific seems (at least to me) that the UPac has the 3985 and 844 down for repairs all the time. then it hit me; the UP only fires them once a year! steam engines were designed to be kept fired up and hot constantly, or at least hooked to a boiler that had warm steam going through them. they fire these things up only once a year for that rodeo train and them moan and groan when they break down so often! News flash, when an engine sits for that long, they seize up and parts break. then you introduce steam into a cylinder that might have coagulated oil in it and the drain cock explodes off. the Durango and Silverton keeps its engines under steam 24/7, and they haven't had to take one of their K-36's down for repairs until the FRA turned into a bunch of a-holes and tightened restrictions on locomotives. If the UP would take a page from their book, and keep the engines hooked to the shop's central steam plant (that and RUN THEM MORE OFTEN!) they would operate smoothly. but the fact is UP doesn't care about its steam engines, they only want more GEVOs and other worthless glorified boxcars! Long live the steam locomotive!!!
