Career
Operators	Chesapeake and Ohio Railway
Numbers	300–307
Retired	1953
Disposition	All scrapped

The Chesapeake and Ohio Railway's class L-2 comprised eight coal-fired 4-6-4 "Hudson" type steam locomotives numbered #300–307 and built by the Baldwin Locomotive Works of Philadelphia, Pennsylvania in 1941. They had roller bearings on all axles, and the first-built, #300, had roller bearings on its side and main rods too. #300 also bore "Elephant ear" smoke deflectors from 1948.

Specifications

Career
Numbers	310–314

In 1947, the C&O ordered five additional and very similar locomotives, numbering them #310–314; these were class L-2-A and differed mostly in using Franklin RC poppet valves instead of the Baker valve gear of the L-2s. These were the last express passenger steam locomotives ordered by a United States railroad, and some of the most expensive at $353,346 each, 80% more than the cost of the 8 earlier L-2 locomotives.

Both classes were among the largest 4-6-4s ever built. They were intended to work the C&O's top-flight express trains on level ground; the railroad purchased 4-8-4 "Greenbrier" types for mountain service.

By 1953, C&O passenger services were wholly dieselized, and there was no more work for these locomotives to do. Hudsons were very unsuited to freight work, with such a comparatively small proportion of their weight on the drivers. All the L2’s and L2a’s were quickly scrapped by 1953 .

gollark: That quote on the right seems wrong.

gollark: It's weird how the system for this somehow manages to simultaneously annoy people who aren't in the wrong constantly, and yet also ignore legitimate issues.

gollark: I imagine they test them in specific scenarios, not really on-road use.

gollark: I hope that wherever you are has an idea of what to do after this.The UK government is refusing to provide details of any plan whatsoever because they don't want to "mislead the public".
