The LT&L brought a handful of MLW S2’s to the roster in 1962; they were durable units, but time (and the two horsemen of increasingly large freight cars & the slow march of electrification) eventually winnowed all of them from the fleet; the last 3 departing in the summer of 2002 after an order of more powerful eco-414s took their places.

Several of the retired units continue to operate in industrial and agricultural switching service, while the last 3 were donated to railroad museums and tourist shortlines.
