AC/DC doesn't really matter since both have their advs and dis-advs. However, Delhi-Metro had a different vision when they started off. Unlike Bangalore-metro, DM went with BG which is common with other commuter rail in India. This needed a redesign of the coaches. The idea of interoperability is not bad at all. That may explain the use of AC.
And when you said "fantastic opportunity to build a modular, upgradable, scalable open source system was botched", were you talking about the stations or the trains? I'm interested to know.
Ride the Bangalore Metro
Anyone rode ..? Howz the experience..
man i have travelled alot abroad and can tell from my experience delhi metro is one of the best maintained and the amount of public it handles and yes just check the pic i am loading the latest racke on the badarpur line is same just the head lights are different and yes the plight is it seems bit less broader as compared to the older onesTrue. However DM is unique as it uses three different rake sources
The DAME rolling stock is from CAF Beasain.
Bombardier manufactures BG MOVIA coaches in Savli, Gujarat.
The ROTEM coaches include both SG and BG units for the first phase trains and SG lines (2 corridor as far as I know)
Delhi metro is atleast 9 years old. We should expect Bangalore metro to be better! Future metros should be even better!
DAME is a high speed metro connection with maximum operating speed of 135 kmph. Bangalore airport HSR connection is going to be similar.
OK intelligent boy tell me any metro system which runs on third rail AC system dude only brtain has third rail system on A.C network for railways not for metros that to they have started to phase out^^^^^^^^^^^^^^
Sorry mate!
Technically speaking, I may not appreciate your 'bs baffles brains' post .
- Who said anything about AC/DC? I'm talking about the power delivery/transfer system only. That pantograph $hit is over 100 yrs. old, sure China uses it on high speed rail too, so what. Outdated idea outdated hi hota hai.
Why do you think I'm sad about this?
The reason is that a fantastic opportunity to build a modular, upgradable, scalable open source system was botched ;( You may be a fan of AC. I would bet the future on DC. DC makes far more sense in Delhi and developing country context, except Edison of GE fame long ago ran away with AC with good marketing. Re: Delhi metro, bet you vested interests played a role. Steel brokers, traders.Because double decker carbon-fibre rakes/coaches will be that much harder to run.
Yeah, double deck, carbon fibre rakes. Coming up!
Can u please explain the bold part please.....^^^^^^^^^^^^
For complex problems like this, one takes a systems approach.
Both train and platform systems. Make sense ?
Technically speaking, systems modules are rolling stock, civil works including platforms, finance system, electrical system, feeder system, throughput/control system, org. system, the k (contractor's ) and sub-k, sub-sub k eco-system.
