well how many people can be contained as max capacity in an average coach? multiply that by 4 and you have the max capacity

cause capacity figures are well different as per site.

Why do you multiply by 4? The max capacity is what rated by the manufacturer as the load it can hold. Anything much greater than that can harm the train's functionalities. Then the newspapers will blame the train manufacturer.

And you forgot frequency ? Capacity of a metro system = capacity per coach X no. of coaches X trains per hour

If capacity per coach is 250 and coaches are 4 and trains per hour = 20 (frequency of 3 min), then capacity = 20,000 pax per hour per direction.

I think he was talking about number of coaches in the train.

yup


but as many sites state originally for the first year or so

it will be a frequency of 5min

so it will be 4 *250*12 =12,000 pax capatiy eventually rising to 20,000 and with 6 coaches and 3 min frequency 6*250*20= 30,000 pax capacity.

I feel that MMRDA has assumed frequency of 90 sec (40 trains per hr) for 60,000 capacity (as mentioned on their website) or assumed 30 trains per hr and higher capacity of coaches (may be 350).

Metro II could be a sight to behold

Mumbai: A 1.5km stretch in the city could become one of the most picturesque urban sights in India. Already, the 4.7-km sealink is a cynosure of all eyes; now, a short stretch on the Santa Cruz-Kurla Link Road could give Mumbai another landmark infrastructure sight to behold.

The sight could be that of a flyover with motor vehicles, and alongside that a metro train or two plying. The Mumbai Metropolitan Region Development Authority (MMRDA) is contemplating changing the realignment of the Charkop-Mankhurd metro line, also known as Metro-II.

The total length of SCLR is approximately 6km. The metro line and the SCLR bridges going parallel will be a stretch of 1.5km from near the SG Barve Marg and the Kurla Terminus area.

MMRDA metropolitan commissioner Ratnakar Gaikwad told DNA that the changes in alignment are being considered since there are too many structures coming in the way of the present alignment. “Though the 32-km-long second line will pose fewer challenges compared to the first, we will be compelled to make certain changes in alignment,” he said.

“The line does not pose any issue while it comes from Charkop taking the Link Road, Linking Road or even SV Road. However, once it reaches Bandra-Kurla-Complex and goes towards Kurla, it would require acquiring and removing several structures. Since we have witnessed massive delays in some of our other projects due to resettlement and rehabilitation issues, we are mooting some modifications in the alignment,” Gaikwad added.

“Keeping this in mind we may take the alignment parallel to the SCLR. Though the final alignment through SCLR is not finalised yet, the metro alignment will hit SCLR somewhere in Kurla and then keep following it till Chembur,” he said.

If the alignment is changed - adding at least 700 m to it - the total cost is certain to go up. Per km cost of an elevated metro is Rs200 crore. “Keeping this in mind, the cost may go up by at least Rs120 crore. Obviously, the contractor will charge MMRDA more. Thus, we have to keep this in mind while changing the alignment,” added a MMRDA official.

saw this article yesterday. almost all the stations coming up are too close to the residential buildings and commercial buildings in the area and not just the weh and ghatkopar stations.

its pathetic indeed. but i dont wanna trust the reporters a lot too. for example, when they say "where will the person land during footfalls", they might just assume something. stations are not complete yet, there will be safeguards for commuters.

However, WEH station, squeezed between two buildings is somethin really bad, too close to the balcony of that unfortunate resident. but this route was the most cramped one from the beginning, this was expected (unless they went underground).

Hope its not cramped on line 2 (except at kurla probably).

well i expect the BKC section not to be cramped on line 2.

Cant say about the rest of the line.

all this would be avoided if they went underground.

I am so sorry to say...but this is absolutely "PATHETIC"....its risk for all.....where was the planning department for MMRC???? how can i plan like this be passed at first place....!!!!
it would have definitely brought down the property rates in that area...people there would be really pissed off....

so sorry to interrupt you guys ...but the whole article makes me sad as i thought new infra development should be done with proper planning with all the above analysis and technology...

Not sure why we are all surprised now. This was expected in Andheri. I live in Andher(West) close to the metro line and it is crowded with no place for any sort of additional construction. I would say that it is an engineering feat that they are actually able to build a metro through these over-crowded and cramped streets withoy pulling down any buildings.

Agree that life for those living next to metro is really going to be tough once the metro starts with all the noise, probably vibrations and dust pollution.

The metro should have been planned to be an unground one from day one. At least this way they would not have to deal with all the PIL's and the Western railway (bridge construction over the existing railway tracks) and life would have been easier for everyone. Would cost more though.

As for the neswpapers, well they need to sell copies.

they should have completed the bandra to colaba line first

which was underground , but now seems to be more elevated by the day

I would rather have one nice line in the city underground than three which are above ground and useless.

This is why i hate the congress. Maharashtra needs Gadkari badly. somebody who can get things done at a decent pace.

also people need to probe how the hell anil gets all the deals. Clearly I dont think his company has the proper expertise for this.

Just look at Ghatkopar station from pics posted in this thread. Does anybody think it can handle the load of all the central railways people who want to change?
