chuggington die cast figures

[pa2k84]

Does anyone have any of these and do you know if they go on the wooden tracks or only the chuggington ones?

They're different sizes. All makes of wooden train seem to work with all makes of wooden track but they're not compatible with the die cast ones.

Thank you very much. Did think as much but figured worth an ask!
