Goosebumps Q1

[SAULGENESISF]

I remember an episode of Goosebumps (the R. L. Stine series), where there was a toy train, and something happened at night to make a ghost train arrive in town, and anyone that got onto it became a toy model passenger on the toy version of the train and was stuck in limbo forever, or something along those lines. I never knew how it ended, and can't find the name of the episode on any website, at least not with the description I am looking for.

Does anyone know what it was called?
