A pretty cool idea. However, the density of the procedurally generated glass panes are a bit too much, making it difficult to break through the glass panes effectively, losing your momentum by a lot. Took me a while to figure out that when you got enough speed that the train turns red, can you break glass.
Generally, pretty good art, nice audio. It's cool seeing that you made a 2D game, unlike the 3D game from the last Brackey's game jam :D (if I remember correctly)
