Greg:
I can help with some of it:
(1)Steam 1518(looks like maybe a 2-8-2?)
1518 was a 4-8-2 class M-78 built by Brooks in 1923.
(2)Steam 804 backs two car passenger train to depot. First is clerestory roof baggage, then more modern coach. Both are Grande Gold.
804 was a 4-6-2 Class P-44 Pacific built by Baldwin in 1913
(3)Steam # 1403 looks like 2-8-2 switching string of coal hoppers, as a Burlington freight with F-Units is pacing it by the depot as 804 sits.
1403 was a 2-10-2 Class F-81 build by Brooks in 1916
