Taken on the 5th of June at 19:41. Possibly situated on the Coryton line.
I've been to Cardiff Queen Street multiple times and trains arriving at Platform 2 always continue towards the right of the diagram, so I'm not sure what the signal circled here is for.
Perhaps it's for shunting between Platforms 2 and 3?
Question from a WJEC Physics Unit 4 paper.
