Wood & Wooden
This category includes both the newer Thomas & Friends Wood (TFW) line and the older Thomas Wooden Railway (TWR) line. Both product lines are basically the same. Fisher Price decided to change the name when they re-designed the line for 2018. TFW vehicles and TWR vehicles are compatible. TFW vehicles are compatible with TWR track and vise versa (TWR vehicles are compatible with TFW track). However, TFW track and TWR track are NOT compatible as the newer TFW track uses unique connectors to fit the track together.
