On the continuing theme of lack of US steam, what could be better than the world's largest loco? The UP Big Boy was made to haul along the Wasatch Range, from Green River, Wyoming to Ogden, Utah. I'm sure this is a well-requested loco, and it would be great to see it perhaps alongside a Union Pacific 4-8-4 (#844)
And also UP SD70M (including America 250 #1776 and #1616 Abraham Lincoln Units), C45ACCTE (ES44AC), C45AH (ET44AC; including #4547 Trump Unit), SD70AH-T4, GP60/GP62/GP60E, SD59MX, and GP40-2/N. Also needed: UP Excursion passenger cars, cement hoppers, intermodal well cars, new autoracks (maybe Thrall articulated or Gunderson Multimax cars), coal hoppers, grain hoppers, steel coil cars, etc.
