Pegita, how does the most eloquent defender of Terri Schiavo know so much about locomotives? You impress and amaze me with your knowledge of railroads.
Thanks for the compliment, Theodore R. ... decidedly undeserved because I copied from the Union Pacific website. (Note to self: ALWAYS source your material!). My parents retired from the East Coast to Cheyenne some years back ... I remembered the Park (but not the name) and the Union Pacific locomotive, "Big Boy." Buffalo were fenced in behind the locomotive ... impressive looking critters, to say the least.
