Train set for library (Lower Tranmere CH41)

My toddler loves to play with the wooden train set at our local library (Birkenhead central), but it's a very small set, missing lots of pieces and with just one train. I'm hoping that someone has any bits and pieces they would be happy to part with so he (and lots of other kids) can play with them. I can arrange pick up and take them to the library, or maybe you could drop them off? Many thanks!
