On their website, Cityrail lists the following travel tips: Arrive at your station a few minutes earlier than your timetabled service to allow sufficient time to board your train. Keep to the left on stairs, escalators and ramps and take care. Spread out along the platform so as not to overcrowd one carriage. Take care on steps and platforms, and always stand behind the yellow line. Stand aside to allow passengers to alight first before boarding the train. Beware of the gap between the platform and train, hold small children's hands. If you are travelling with a pram, travel near the guard's compartment. Board the train as quickly as possible and move inside the carriage to allow others to board behind you. Do not obstruct the doorways. Vacate priority seating for elderly or less mobile passengers. Please do not sit on steps or put feet on seats. Do not hold the doors open or attempt to board the train after the whistle and 'doors closing' warning has been
