#RailNatter Episode 167: Why do crossing noses crack?

Our very special pilgrimage site of Colton Junction suffered a catastrophic (but all too common) failure this week, and so it seems like a good chance to talk about crossing noses, what they are, why they fail and how we can stop them failing. May or may not include gratuitous imagery of Colton Junction's fabulous equal splits. Enjoyed this?
