Toby 0-4-2T narrow-gauge freelance

Toby is a freelance 0-4-2 tank engine designed by Steve Eaton to be as simple as possible. It is probably the cheapest way to get involved in coal-fired live-steam passenger hauling. The boiler is of the marine type, and the loco is fitted with slip-eccentric valve-gear. Like many free-lance designs the locomotive can be finished to suit the builder's whim, so there are many detail variations to be seen. The side-tanks do not contain water but are filled with weights to aid adhesion.

It has proven to be a popular design and many can be seen running. The 0-4-2 wheel arrangement gives it more stability than a basic 0-4-0 and the loco has a reputation for being very free-running although there can be an issue with the marine type firebox ashpan filling as the available space is limited.
