I promise to stop riding this logo design hobbyhorse soon and turn to another topic, but first, look at these spiffy emblems for mostly long-gone US railroads! These geographically nostalgic items and many more were assembled by designer Christian Annyas.
Some of these samples seem a mite fancy pants. (left: Delaware Hudson Railroad, 1889; right: Atlanta Birmingham Coast, 1926; below right: Baltimore Chesapeake Atlantic, 1905)
At left and below are three of my favorites in the representational vein.
Below, Detroit, Memphis, and Frisco seem fairly jaunty for the time period (late 19th century), whereas I love the yin/yang thing of Northern Pacific and the typographic experimentation with the next three.
If I've made a train enthusiast of you, why not peek into Nothing Like it in the World: The Men Who Built the Transcontinental Railroad 1863–1869?
