The range comprised of two steam-outline locos, an 0-4-0 and a 2-6-0, available in clockwork and 18 V AC electric, a railcar, also in clockwork and electric, and a number of four-wheel and bogie passenger and freight cars, together with track, points, crossings, buffer stops, signals, a level crossing, lamps and a transformer.
