Tram Secrets 電車謎


Life-guard Sets

When the life-guard gate (broom like) react, the life-guard tray glide instantly for preventing people getting injured.

However the removal on either old or rebuilt trams began during the refurbishment in the mid-1980s, a hearsay is due to some incidents on trams that the life-guard tray will have jammed by cartons and friction causes fire.



Tolling Car

Tram 300 often manages for positioning the trams/trucks undergo overhaul. Pictured above is tram 300 “connects” a truckless tram 53 stood on the accommodation truck by using a crowbar link up the medium “hole” of the bulkhead of each other.


Diesel Fuel Tram?

Smoke release like diesel fuel train when tram 300 runs in diesel fuel, with trolley hooked on the roof.


“Top” Secret

The secret inside the roof-box!! The black wires are likely the electric resistance use as “voltage divider”, transferring the electric current to the motors.  This is not applicable for IGBT trams, their roof-boxes only for consistencies to those non-IGBT trams.

電阻箱內的黑色物體相信就是電阻。電車行駛時,電流會經過電阻通往兩組摩打。度字車用來作voltage divider,斬波車就不需要電阻箱,只是為了統一車身外型而被保留。

There can always be flashing on trolley when it passes the traction (section insulator) of the wire with electric currents if the tram did not reduce the speed while cross the “double-white line” on the track. The trolleywheel is thus damaged and the graphite is burnt away and it has to be replaced.
This is a funny signage showing the man-operating procedure of changing the traction and the direction of the trolley (using a bamboo stick), both have to be consistent.
