CPKC acquires ‘new’ power

Two red locomotives and one blue locomotive on freight train with grain silo in background

Just shy of two years after the CPKC merger, the Class I railroad has purchased its first “new” locomotives. The eight General Electric ET44ACs were originally an order for Baffinland Iron Mines located on Baffin Island in Canada. The new-build mine project to haul iron ore to seaport via rail has been delayed many times, […]

Amtrak SDP40F diesel locomotives

Silver Amtrak SDP40F diesel locomotives with red noses sit outside brick building

Amtrak SDP40F diesel locomotives were derived from the best-selling SD40-2 platform but were far from a success on their own. The SDP40F shared its 72-foot, 4-inch frame with the predecessor passenger unit FP45 from 1967. Internally, however, it was akin to a 3,000 hp SD40-2 with a steam boiler added. That should have been a […]

General Electric’s U23B: Where are they now?

Two yellow locomotives leading freight train

General Electric’s U23B General Electric broke into the domestic road-switcher locomotive market over six decades ago with its U25B model in 1961. The U-series line would continue to evolve and grow, laying the foundation for the company’s ascent to becoming the No. 1 locomotive builder in North America in later decades. The U23B was essentially […]

Illinois Terminal locomotives remembered

Diesel Illinois Terminal locomotives pull maroon passenger cars

  Illinois Terminal locomotives included steam, electric, and diesel over its existence.   The Illinois Terminal was an electric interurban line serving western Illinois down to the St. Louis area. In the mid-1950s the railroad abandoned its electric operations, moving to all-diesel operation — the last steam ran in 1950, and dieselization had begun with […]

U.S. Sugar 148 enjoys the spotlight

A color photograph of a steam locomotive pulling more modern passenger cars

I haven’t counted every last owner one time or another of Florida East Coast 4-6-2 No. 148, but it must be close to a record. For a mainline-size engine, the Pacific was incredibly peripatetic, sort of like former Burlington 2-8-2 No. 4960 before it landed at the Grand Canyon Railway. The 148 emerged from Alco’s […]

Amtrak NPCU ‘Cabbage’ locomotives

Amtrak locomotive on track in city

Amtrak has been using unpowered F40PH locomotives for decades in various corridors across the country. For its shorter-distance trains — where one or both ends of the run lack turning facilities — these units allow Amtrak to assign only one powered locomotive instead of two. The first F40PH converted was AMTK No. 200, which had […]

The ‘Wabash 50’

A black and white photograph of a steam locomotive

  Few, if any railroads, duplicated what the Wabash Railroad did in 1930 and ’31 when it ordered 50 big locomotives from the Baldwin Locomotive Co., split half and half between the tried-and-true 4-8-2 wheel Mountain type and the still relatively new 4-8-4 Northern. It was a remarkable decision, given the slight differences between the […]

Atlanta & West Point locomotives remembered

Smoking steam Atlanta & West Point locomotives with freight train

Atlanta & West Point locomotives were carefully curated alongside those of its sister roads.     Although much of the West Point roads’ 20th-century steam locomotive fleet looked like the “Georgian Locomotive” memorialized by H. Stafford Bryant Jr. in his book of the same name — a handsome, elegant group — perhaps the most interesting […]

Model steam locomotive driver flanges

Q: Why are the flanges on model steam engine drive wheels so much larger than on the prototypes? Is it because the models don’t weigh very much? Or is it because they have to navigate tight curves? And do larger scales (like G scale and live-steam models) have flanges that are closer to the prototypes? […]

Locomotive pilots 101

Side view of hoses and cables connecting a locomotive and slug unit

A locomotive has two pilots, one on each end where it interfaces with other units and/or the cars its hauling. The main component is the coupler on each end, along with the adjacently mounted train line air hose. These are the basic connections between all freight cars and other locomotives. Working outward from the coupler […]
