Tram Secrets 電車謎

Standard

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.

當前方的救生網閘受到撞擊感應時,這排橫木式的救生網盤便會滑下,防止傷者被捲入車底。

但一個如此好的構思在八十年代翻新時期被取消,據聞因為曾經有電車行走時,救生網盤被紙皮卡住拖行而著火。是否屬實不得而知…

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.

300號一般負責運送維修中的電車/底盤。300號拖車時,工人用一支鐵鉤連接兩部電車的泵把中間位置,然後鎖緊,便可以拖行。

Diesel Fuel Tram?

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

300號使用柴油驅動時,拖里會被拉下,上層缺口會噴煙,猶如柴油火車。

“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.
當電車經過「分段絕緣器」時,需在路軌的雙白線前減速,若不的話,拖里的轆頭會因電流而產生火花損毀,需要更換。
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.
這是個有趣的標示牌–「扶落」估計是指,工作人員用勾竹將拖里調動至電纜的轉向夾口時,需要確保天線和路軌的夾口對應。
