Sherman Hill for TSW would be great. I think it needs to be set in either the present day or the 1950s. Engines for the modern version: UP ES44AC or ET44AC, UP SD70ACe (T4), UP SD40-2, UP DDA40X Centennial #6936, UP SD70M (with flared radiators & flag), UP SD60M, or UP GP38-2 Also include the restored steam engines: Big Boy #4014, Challenger #3985, FEF-3 #844 Engines for 1950s version: UP Big Boy, UP Challenger, UP 4-12-2, UP FEF-1/2/3 4-8-4, UP F3/F7 As & Bs, UP ALCO PA As & Bs, UP GP7/9, UP SD7, or UP Gas Turbine Also, the route needs freight cars and passenger cars, plus a caboose for the vintage version.
