I thought this was an amusing size comparison between these two modes of transportation.

Taken from the Missouri side of the Mississippi River; 6630 looks rather minuscule below the giant power line tower.

352 leads a train south into the yard under the the south approach of the MacArthur Bridge, with downtown St. Louis rising behind them.

Six Union Pacific locomotives roll east across the bridge in the early morning light.

Rolling west through town in the late evening; headed for Kansas City, MO.

Heading east, with sister unit 3855, past the Western Auto building. In the foreground is part of the walkway between Union Station and Crown Plaza.

Leading a west bound UP auto-rack train.

A crew member flags traffic on old Route 66 as 2587 backs cars into the US Silica plant.

A rainbow of BNSF locomotives lead a train north along the Mississippi River bluffs.

BNSF 703 along with Ferromex 4624 lead U-SEMBIR south over the TRRA's river-front-high line. (U-SEMBIR is an iron ore train.)

An ex-Chicago and Northwestern Operation Lifesaver unit works DPU duty on a south bound coal drag along the Mississippi River Bluffs.

The emblem on the side of steam locomotive 1015 rusts and bleeds. According to the museum plate on the locomotive's cab, 1015 was the first engine the museum received.

A UP coal drag passes to the far left as the sun casts the first rays of dawn on the Cuba Subdivision.

Heading north on the TRRA with a rainbow assortment of engines. The second unit is BNSF 6106, an EMD SD9.

A string of tank cars rolls south over the KasKaskia River on a south bound freight.
