Proper drainage system should be installed along the tram line at regular intervals and at the necessary locations (such as the lowest point of the water area and vertical section).
The trench drain water discharge pipes should be connected to the drainage system of the nearby road or a separate drainage pipe.
Trench drains should be easily cleaned to remove sand and other debris.
The laying of the trench drains should not affect the support or guiding function of the rail.
The trams in Bordeaux, France, use steel-wheeled rail trams, which have a mature tramway drainage system and track-dedicated drainage facilities. The groove track is perforated at intervals, and the rainwater in the track groove is collected into the transverse groove through the hole, and then discharged into the municipal rainwater pipe network through the transverse connecting pipe.
