In a heavily polluted city on an Earth-like world, the Fourth Doctor assisted the Guardian Angels in finding the correct train track which would lead them out of the city and to the countryside. However, when he arrived there in the TARDIS and waited for them, they never arrived, and he concluded that they didn't make it, which was perhaps just as well since the countryside was just as polluted as the city itself. (COMIC: End of the Line)

In the Matrix on Gallifrey, the Fourth Doctor found himself trapped on a recreation of a train line, his foot caught in the tracks after the points changed, while Goth drove a train toward him.
