When I had to travel by train I biked to the station, found the most unassuming and out of everyone's way place to park there is, and chained my bike to a fence. When I came back I saw it was still there. But what was more: it had note attached to it. It had been illegally parked! I was a bit confused. Where are you supposed to park it then, if there are no racks? But the note provided the answer: these are inside the station! On one of the platforms... and indeed. Next time I parked it there. But can you imagine if in a Dutch town of ~250.000 people you would try to fit all the bikes on a platform!
So this is it: all the bike racks for Plymouth railway station!
