So, some plane clothed guy came up to me at a station today and said "Excuse me Sir, I'm a police officer, can I just ask you a few questions?" and showed me his warrent card.

"Okay...."

"What do all these mean, 13a, 13b, 13c, what is that?"

"Uh, well, there different sections of the platform, a train might stop in 13b instead of a...."

"Oh okay, so where would a long train stop then instead of say a shorter one"

"Well, depends on the type of train I guess, there are little signs that say where a type of train is supposed to stop and the car / length...."

"Oh okay, thank you Sir"

So I went on my merry way, properly confused by it. It later occured to me I was wearing a high-vis vest at the time relating to my job which might have seemed suspect but even so, quite bizzare.

Anyone ever had that or know WHY that would occur?
