Locomotives seen from the St. Louis River trail

[Zoohogger]

Made a trip to St. Louis for the purpose of bicycling the Katy trail and the Mississippi Greenway trail which meanders between the river and the industrial district north of the arch.
A few of the switchers that I saw along the way. FTRL had 2 other geeps that I could see and 2 end cab switchers. Must be a busy place.
Plus the McKinley Bridge, with what look like catenary. What Railroad or interurban was this and where did it go?

Illinois Traction/Terminal Railroad

From the Wikipedia article:
The McKinley Bridge across the Mississippi River, originally built in 1910 to carry the Illinois Traction System's trolley cars over the river to St. Louis, survives to this day. Some sections of the Illinois Terminal Railroad and its affiliated lines have become rail-trails, such as the Interurban Trail south of Springfield.
