The first RS-11s were produced by Alco in early 1956. This locomotive, classified by Alco as model DL-701, was their replacement for the very popular RS-3 road-switcher. Featuring a V-12, 1,800hp 251B diesel engine, the RS-11 was Alco’s answer to EMD’s very successful GP9. The turbocharged RS-11 accelerated faster, had a higher tractive effort rating and typically used less fuel than the competition. It was also quite versatile and could be found in heavy haul freight as well as passenger service.
The largest owner of RS-11s was Norfolk & Western, which purchased a total of 99 units (an additional 35 were added to the fleet after the merger with Nickel Plate). Other major purchasers included Northern Pacific, Pennsylvania and Southern Pacific, all of whom placed repeat orders. With approximately 426 units built for the US and Mexico over 8 years of production, the RS-11 was successful for Alco in that it provided ongoing competition for EMD’s popular road-switchers. A few examples of this model are still in service today and can be found working for various shortlines in the US.

The locomotive wears the road’s distinctive harvest gold and green scheme, already showing signs of weathering as traffic declined in the early 1980s. Industrial buildings and stored equipment frame the scene, capturing the worn, workaday atmosphere of the period. © Greg F. Brewer

One of just two RS11s operated by Maine Central, the locomotive had been withdrawn following a broken crankshaft. Built by ALCO in June 1956, No. 801 still wears its faded Harvest Gold and Pine Green livery as it awaits the torch, leaving sister locomotive No. 802 to briefly carry on alone before its own retirement and scrapping the following year. © Dan Raymond

Built by ALCO in June 1956 as Pittsburgh & Lake Erie No. 802 and later renumbered P&LE No. 5762, the locomotive joined the Maine Central fleet as No. 802 in 1974. It is seen here wearing the railroad’s green and gold paint scheme during the final years before the Guilford era. No. 802 remained in service until 1988, when it was retired and sold for scrap. © Warren Calloway

Modelling
Here are some details worth considering when refining an N scale RS11. The list focuses on features seen on the Maine Central units (801–802), which were equipped with dynamic brakes and screened carbody filters below the brake blister.
Add sand hoses to each wheelset.
Fit grab irons above the number boards.
Include an axle generator on one truck.
Represent truck inspection lights
Omit the roof grab irons, as the Maine Central units lacked them.
Replace the handrails with finer etched or wire versions if possible.
Check that the carbody filters are of the screened type, correct for the prototype.
