When we were close to finishing the filming we were approached by the station manager and he explained to us that it was prohibited to film on public transport without permission.
This was a easily avoidable situation. i asked him whether we can continue filming today as we were almost finished, and he replied saying it was okay to continue for today but next time we would have to ask permission.
He told us the reason for this is safety, we had to film from many different angles and the manager was worried that we might inadvertently fall into the tracks.
But this was one of many minor issues we faced but we managed to overcome it.
