  I saying signalling =.="

   

  Every station they got signalling system. I usually like to walk slowly pass the flapgates and peek in the board.

   

  When there is a train at Zone 1, Zone 1 light will light up

  yeah sth like this

   

  Crossover requires 4 switches. 

  Scissors crossover requires 16 switches. XD

  Erm, I have an question for that as well, what if there are a lack of trains (Meaning if a C651 got broke down but the nearest C651 available is probably more than 5 ~ 6 stations away then how?)

   

  C651 is the minority population in the SGMRT. (Only 19 cars)

   

  All couplers on the NSL/EWL are compatible ( I not very sure about C830 and C151 or other trains ).

  If you want to couple 001/352 (The depot staff really cock-eye leh), It can move but 001's motor will go BOOMZ, because 352's motors are too powerful. C651 and C751B can have a code to downgrade to 4Q Chopper but i doubt SMRT did that. thats why, you won't see any cross coupling.

  2 for normal crossover, 4 for scissors.

  0.o Ps my bad then.

   

  @wills_Chong 0.o,

   Then if you walk pass the station center can see loads of button like at tampines, got 4 buttons 0.o

  Not all stations have the board hor. Tampines got 4 buttons because got 2 crossovers.

  Of cos cannot cross-couple la, but if u wan a cross-coupled sound effect of the engines u can go edit yourself :P
  
  Last time i asked a SMRT technician he already said its not possible.

  Any train can be coupled to the defective train. A C651 may breakdown, and a C751B came to rescue it. Vice-versa, same goes to the C151's.

  Eh. One day, lets go train camp, wait for 1 C651 and 1 C151 depart together, then record XD

  Stations with a crossover left or right of the station have only. e.g Boon Lay, Joo Koon. Wanna peep, Joo Koon's the best.
  
  But must understand crossovers, not any direction oso can. No matter where the train is going to turnback, THE LIGHTS MUST BE VISIBLE to the other train of the opposing direction, or else 'bang'.
  
  In a double-crossing, there is a limit to where the train can go to, then u wil see a permanent red-light. That is when if a train opposes the usual direction.

  Couplers used are fully automated couplers. 

  There is no way, and it is impossible to have C751B motor car coupled with a C651 motor car. 

  Reason is because, each train (6-cars) have two sets of EMU. Which means, there are two sets of EMU in a 6-car train.

  1 set of EMU contains: 1 DT - 1 M1 - 1 M2.

  A C151 EMU set, can only be worked with a C151 EMU set, not any other EMUs. This explains why, there are quite a number of miscoupled trains, spotted by other train fans.

  Agree. But anyone got idea where is 216 and 225? Vanished into thin air?

  In other words, different train models will in theory be able to mechanically couple together mechanically, but not electronically. Correct me if I am wrong.

  Next station and arrival is by ATAS. The suspicious and no eating/drinking is auto and has a pattern.

  I'd like to comment on something which pertains to a potential copyright issue by the advertiser/SBS Transit on the NEL(and on some buses).

   

  I should post it here or should I create another thread?
  When I saw it I was really shocked with the similar with another rail operator halfway round the world.
