Thomas and Friends Coming to Train Sim World in 2025
In an interview video between Dovetail Games and Mattel producer Ian McCue and executive producer Matt Peddlesden, they share what to expect about the upcoming update, as well as how the collaboration came about. According to Peddlesden, the developers wanted to collaborate with the franchise for the longest time, though noted that there were several complicated hurdles in order to do so. The opportunity came at the right place and time in order to bring Thomas intoTrain Sim World 5, giving players a story-driven experience while they also do the expected tasks ofaTrain Sim Worldgame.
WhileThomas the Tank Enginehas been added as a modto various games before, likeFallout,Resident Evil,Silent Hill, and evenElden Ring, those were usually done for comedic contrast.
