The Swiss firm of Erno (ERnst NOtter, Unterägeri, near Zug) produced 0 gauge tinplate trains from 1945-1949. Its sole motive power was an electric-outline 0-4-0 clockwork locomotive, inspired by the well-known Märklin RS900. The loco was available seperately in green and brown, and in two-tone purple/cream, red/cream and blue/cream in train sets. A very few locos were made with an electric motor. Erno’s first rolling stock in 1945 consisted of four-wheel goods vehicles; a van in brown and in white (lettered Bierwagen (beer van) or Kühlwagen (refrigerator van) and a tankwagon coloured and lettered for Shell, BP and Esso. All these had an extended chassis at one end to accommodate a brakeman’s hut. With tbeir length of 175 mm they were quite well proportioned. When Erno also produced four-wheel goods wagons without a brakeman’s hut and (from 1946) a four-wheel coach, they used the already available chassis, resulting in these vehicles all having an assymmetrical wheelbase. The initial success of Erno was nullified when Märklin returned on the Swiss market in 1947; Erno could not compete on price and production was ended in 1949. Production machinery and remaining parts were bought by other Swiss 0 gauge producers Buco and Resal.
