It is RS-"one"; the first Road Switcher (RS). (Their switchers - no short hood - were "S-1" and the like.) In fact, Alco was the first to use "road switcher" as a term, so far as I know. Later came the RS-2 and RS-3 (almost identical visually), and some other RS's, then they quit using the term.
He’s talking about a transformer, the RS-1 (Lionel 6-12780), not a locomotive.
A 50-watt transformer is not a decent starter model. It’s underpowered. So forget the RS-1 and focus on a 75- to 100-watt transformer instead.
