Erie O Scale Premier Alco S-2 Switcher Diesel Engine w/Proto-Sound 2.0

Buoyed by a moratorium on competing diesel switcher manufacturing during World War II, the American Locomotive Company was able to cement itself as the premier switch engine manufacturer of its day with the release of its S Model engines beginning in 1940.

Designed to replace the hi-hood Alco diesel switchers of the previous decade, the low-hood S-1 thru S-6 models were incredibly successful, with over 3,200 produced by 1961. Just over 1,500 S-2s were produced, outfitted with a turbocharged 1,000 horsepower 6 cylinder diesel engine that greatly improved upon the nearly 700 horsepower S-1. In fact, the S-2 proved to be the most successful of all the S Model switchers, capable of mainline passenger or freight work in addition to the usual yard work handled by most switch engines.

Returning to the M.T.H. Premier Line in all-new schemes, the Also S-2 may be one of the finest O Scale switchers ever produced. One listen to its Proto-Sound 2.0 locomotive start-up sequence, followed by a quick run in the switch yard, is proof-positive that this is one serious little locomotive.
