Doctor Who
I've thought for years that this is a great film and ripe for an homage within the infinitely flexible format of Doctor Who. Following lots of other classic horrors being similarly used to excellent effect by the series. So: the TARDIS materialises on a train (period setting always a good idea)... there's a murderous (alien?) cargo... competing forces among the passengers... and all trapped in motion through bleak countryside etc...
Then, this year, the episode Tooth and Claw actually reused one notable element of Horror Express' plot. (So far entirely unacknowledged and possibly even coincidental.) BUT it wasn't any of the above! The opportunity remains, therefore!
