I just noticed, in Prague Metro train, that on the info display it says:
Florenc - change to line C
In Prague, we just have three subway lines - A, B and C. But I always thought the correct word for switching transport vehicle is transfer, not change. But I'd also be surprised to find an error in public transport info sign.
Is change also valid word in this context? If so, are there cases where one is more valid than another?
