You can go overboard on that. Here in the UK we don't have any crossing of the tracks at stations, but there are pedestrian level crossings where footpaths cross the track.

Sadly, due to a few recent incidents where people obviously don't understand the warning to "Stop, look, listen, cross quickly" Network Rail have begun to take a zero tolerance attitude and these footpaths are being taken out of use. In some cases tunnels or bridges are being substituted at truly ludicrous expense.
