this is a wooden train with cargo blocks and an abacus engine.
it is a toy, but I would only recommend it for decoration.
one of the slats on the side of the car has come off, can be reglued, but that is what makes me think it would work better as a decoration only.
might be cute at Christmas, under the tree, as a decoration.
the train has 23 blocks, and each of the 6 sides of the blocks has a number or letter.
so it has the complete alphabet and numbers 1-10 but not all at the same time, as there are only 23 blocks total.
the engine measures 4 inches high and 5 long, and 3 to 4 inches wide.
the cars don't hook together, they set together, see pics. they have holes, but no pegs, they could be hooked if you had pegs.
over all a very cute item.
