It's been over two years since we've done a proper alternative history episode (Episode 7 was on what might have happened if the APT had made it) so for Episode 125 it's only right that we look to the InterCity 125 (a.k.a. the High Speed Diesel Train) and have a think about what might have happened if it had simply never come into existence...

What might have changed? Would the railway renaissance that came about in the 1980s never have come to being without them? Might we see a very different-looking railway network today had they not appeared and been so successful? Tune in to see what I reckon!
