1. It is still a medium capacity. Pax still can take
190/700/700A to the city. Since when DTL plies Bedok?
2. If you talking about space there's a big difference. You
failed to take consideration of residential area proximities, civil
structure, max load, whether it's a soft ground or hard ground.
Pantograph system is expensive and not reliable. High maintenance
cost to change the cables if there's any faults and there will be
service delays.
1: Since DTL Stage 3 have to ply between Chinatown to Expo, and
interchange with Rochor, MacPherson, Tampines and Expo, it has to
via Bedok Resevoir. Dont forget that DTL Stage 3, to be completed
in 2016 (Or 2018), is part of the former rectangular loop of
Eastern Region Line (Northern sector).
2: Ok, I did not take that into consideration because along
North Coast / Shore line (Especially Northen part), have not
developed anything yet! For Eastern area, such as Pasir Ris, seemed
to me is possible. And why i suggested another Pantograph system
such as NEL is because of provisional tunnel in Punggol. Whether
that will come true or not, is not I can determine one. And, so
far, the cables issue only happened once in Outram Park NEL. Since,
all future lines will be fully underground, I dont expect service
delays due to cables being struck by thunder and such.
