and/or sirens, keep off the road. 

32. Buses.  Get on or off a bus only when it has stopped to allow you to do so. Watch out for cyclists when you are getting off. Never cross the road directly behind or in front of a bus. Wait until it has moved off and you can see clearly in both directions. 

33. Tramways.  These may run through pedestrian areas. Their path will be marked out by shallow kerbs, changes in the paving or other road surface, white lines or yellow dots. Cross at designated crossings where provided. Elsewhere treat trams as you would other road vehicles and look both ways along the track before crossing. Do not walk along the track as trams may come up behind you. Trams move quietly and cannot steer to avoid you. 

34. Railway level crossings.  You MUST NOT  cross or pass a stop line when the red lights show, (including a red pedestrian figure). Also do not cross if an alarm is sounding or the barriers are being lowered. The tone of the alarm may change if another train is approaching. If there are no lights, alarms or barriers, stop, look both ways and listen before crossing. A tactile surface comprising rounded bars running across the direction of pedestrian travel may be installed on the footpath approaching a level crossing to warn visually impaired people of its presence. The tactile surface should extend across the full width of the footway and should be located at an appropriate distance from the barrier or projected line of the barrier.
