He is also brown instead of maroon red and does not have a boiler. The Wooden Railway merchandise line for the Thomas & Friends franchise was created by Roy Wilson of Learning Curve in 1992, with the line becoming publicly available in 1993. These original models were primarily constructed with painted wood, along with metal used in the coupling magnets and axles and plastic for the wheels and faces. These models were relatively simple, with simple wooden stubs for the funnel and dome, while details such as windows, whistles and buffer beams were omitted.

The Talking Railway Series was a range of interactive engines and playsets. 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. 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. In late 2011, TOMY bought out Learning Curve and as such acquired the rights to the Wooden Railway line. They sold the products previously planned to be released by Learning Curve for early 2012. The products due to be released in late 2012 coinciding with the special Blue Mountain Mystery were cancelled because Learning Curve had only developed the computer generated prototypes, before they were acquired by TOMY. Most of these cancelled releases with the new CGI style models were re-constructed by TOMY and sold under their name and a few others were later released by Fisher-Price. TOMY held the licensing until the end of 2012. Volume VII (Note: Tiger Moth's propeller differs from the production model, suggesting the one seen here was a prototype) Thomas has the most variations of any character in the Thomas Wooden Railway, with more prototypes, changes, and variants than any other character in the range.

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. At 25 years, Wooden Railway was the longest-running and most popular Thomas & Friends merchandise line (with ERTL being the second longest-running at 20 years). In late 2016, some engines received smaller faces that no longer cover the whole smokebox front and others' faces were changed. Features Skarloey with Gravel Cars; Gravel Cars are repaints of the Boulder Cars from Rheneas and the Boulder Cars.

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. Fergus' reintroduced model has entirely white wheels despite his original model having the correct red wheels with a white rim. Features Soap-Sud covered Thomas with red funnel, soap suds covered Percy, bubble liquid car and hay covered Sir Topham Hatt's car. The second known prototype of Thomas seen features six red HEROS wheels, no coal bunker details, and a face borrowed from Thomas's ERTL die-cast vehicle.
