A total of fifteen characters exclusively from the Railway Series have been released in the Wooden Railway range. However, before Mike was introduced to the television series, a total of sixteen characters were released. These improved designs were manufactured until 2002, when they were replaced with a third generation of design, which included new and more detailed faces. 2011 saw another slight re-design in the form of new faces to coincide with the recent CGI Series switchover. The most famous of all the vehicles on the Island of Sodor, Thomas the Tank Engine is considered by all to be a "really useful engine". He is a cheeky, fussy little engine who is always eager to help. 2018 box description

Initially released with Bertram and the Scrap Cars; later reissued individually in 2012 and 2016 for limited release. Bertram's original model depicts him in his proposed tank engine form, with a completely new design. In his TV series appearance, he uses Duke's model with Smudger's face. When he was reintroduced in 2016, he was given a tender, but retained his bunker. While Whiff's model has the correct amount of wheels, this results in him being longer than engines who should be the same size as him. Features Soap-Sud covered Thomas with red funnel, soap suds covered Percy, bubble liquid car and hay covered Sir Topham Hatt's car.

Features Skarloey with Gravel Cars; Gravel Cars are repaints of the Boulder Cars from Rheneas and the Boulder Cars.

The engines have special gold magnets which, when they are at a destination, will prompt the Fat Controller to greet them. This range is discontinued.

In late 2017, twenty-five years after the debut of the Wooden Railway line, it was retired and replaced with Wood. The replacement was originally announced to take place in 2018, but ended up happening sooner.
