Gosh, I know that, that's such a stupid mistake.
The full sentences are:
"The train will stop if any part of the train is in the station otherwise it will continue to the next stop where help can be more easily given" (sign on the tube, I do realise it's correct, I was just wondering if the other option was also possible)
and
"Yes I am rambling, can you tell that I am trying really hard to not read?" (also written by a native speaker)
Well, thanks a lot!
