cover of a D&RGW "booklet," undated but probably mid-1930's,
no credits. The cover shows 4-8-4 #1702, one of the first
such engines the D&RGW had (1700-1713). They replaced the
3 cylinder 4-8-2s (1600-1609) in passenger service and operated
without a change (only servicing stops) between Denver and
Salt Lake City.
