00:00 This station is 475 meters long.
00:03 It is about half a kilometer long.
00:06 This center track will be used for the purpose of train reversal
00:12 and to bring the train in the stabling line.
00:15 This is called a platform screen door.
00:17 It will only open when the train stops.
00:20 Simultaneously, this will also open along with the train door.
00:24 A corridor can be made underground.
00:27 We can easily connect the two corridors with the help of BKC authorities.
00:33 So, the bullet train will also be connected to the metro.
00:35 Yes, we have that provision.
00:37 Hello, I am Vinayak Parabguna.
00:53 Welcome to LokSatta.com.
00:56 In the previous episode, we understood the location of the dam
01:01 that flows under the Meethi River.
01:07 It is amazing that the river is flowing from the top
01:10 and the metro is going down.
01:13 We understood the precautions taken to protect the metro.
01:19 I am at the BKC station of the metro.
01:23 I should say the station on the track
01:27 because we can see the track on both sides.
01:30 One track is coming from one side and the other is going to the other.
01:34 This means that this is a junction station.
01:37 This junction station has a lot of uniqueness.
01:42 It is said that BKC is one of the biggest metro stations in the world.
01:49 It is a very important station.
01:52 We will understand the different stories behind it.

02:40 Once again, we have with us the MMRCL's executive director,
02:57 Suyash Trivedi.
02:58 Mr. Trivedi, welcome to the show.
03:01 We have heard that BKC is the biggest metro station in India.
03:06 It is also one of the biggest metro stations in the world.
03:12 What is the reason for this?
03:15 BKC is the longest metro station in India.
03:26 I think it is one of the longest metro stations in the world.
03:33 The reason for this is that it is a mid-terminal station.
03:38 Mid-terminal station means that some trains terminate here and some continue.
03:45 Like a junction.
03:46 Yes, like a junction.
03:47 The train that terminates here, you have to reverse it.
03:53 There are reversal facilities at both ends of the station.
03:57 Because of the reversal facilities, we have to make the box of this station according to the accommodation of the reversal facilities.
04:06 The length of this station is 475 meters.
04:10 475 meters.
04:12 So, you can say that this is a station of about half a kilometer.
04:16 Usual stations are of 200-250 meters.
04:20 But this station is of about half a kilometer because there are reversal facilities at both ends.
04:26 We can see two different types of tunnels behind us.
04:31 One tunnel is going towards Dharavi.
04:35 The other tunnel behind us is different.
04:38 Why are there two different types of tunnels?
04:42 BKC station is a unique station in this regard.
04:47 There are three tracks and two island platforms.
04:51 The tunnels you see on the right hand side are made with the help of NATM technology.
05:00 This is the down line of this system.
05:03 The tunnel in the middle is made with the help of NATM technology.
05:09 This is used as a stabling line.
05:12 I will explain the stabling line to you.
05:15 The third tunnel is on the side of this.
05:18 The second tunnel is on the up line.
05:21 Both are main lines.
05:23 The stabling line is used to increase the efficiency of the operation.
05:29 We have planned to park two trains at BKC station at the same time.
05:34 So that you can increase the operational efficiency.
05:38 If you want to introduce trains in the system, then the train will be introduced from the depot.
05:43 In addition, trains can be introduced from BKC station.
05:46 Similar provision has been placed at the other end of the tunnel.
05:51 Let's say that the metro service is going to start at 5 am.
05:59 One train will leave from the depot and the other train will leave from here.
06:04 Correct.
06:05 But the construction of this tunnel is also different.
06:12 The main line tunnels are made with the help of NATM technology.
06:20 NATM technology is used for excavating by using mechanical means.
06:28 As soon as you excavate, you have to support the ground immediately.
06:34 If you excavate the ground and do not support it immediately, there is a chance of collapse.
06:40 So we call it a temporary support system.
06:46 Subsequently, when you come back and support it permanently, we call it a secondary support system.
06:56 This tunnel is also going under the Mithi river.
07:01 Oh, okay.
07:02 So this is one tunnel and this is also under the Mithi river.
07:06 So this part is on the ground surface and this part is going under the Mithi river.
07:10 So the entry exit number 2 is in front of you.
07:16 It is the Audit Boman building.
07:18 There are 7 entry exits in BKC station.
07:21 We have taken care that passengers have to walk a minimum distance to reach their destination.
07:28 There are 4 entry exits at the ITO junction so that they do not have to cross the road.
07:35 There is another entry exit at the north end and this is the southernmost entry exit.
07:41 We have taken care that passengers have to walk a minimum distance to reach their destination and they do not have to cross the road.
07:48 Sir, earlier we were standing on the track and now we have come to the platform.
07:53 You had told us about the uniqueness of this platform.
07:57 BKC station is a unique station in terms of number of platforms in line 3.
08:05 Normally, other stations have one island platform.
08:11 Island platform means that there is a platform in the middle and there is a track on both sides.
08:15 But the uniqueness of BKC station is that there are two island platforms because there are three tracks here.
08:22 Because there are three tracks, there is one island platform and the other is in the next.
08:27 We are standing near the upline which will run towards the Aarey.
08:34 Let's show you the central line.
08:37 Where is this line going?
08:41 This is the central line.
08:44 It is not going anywhere. It is going to stay here.
08:47 Because we are going to use this central line for reversal and for the stabling line.
08:54 The parking that you had told us.
08:56 As I told you, this is a mid-terminal station.
08:59 Some trains will go straight ahead and some will be reversed.
09:03 This central line will be used for the purpose of reversal of the train and to bring the train in the stabling line.
09:12 Apart from that, you can see a platform there.
09:16 That is the second island platform and there is a track beyond that.
09:21 And the trains will run towards the Kuff parade on that track.
09:25 So, this is the track that we saw earlier and it was going to go towards the Aarey.
09:29 Now, it is going to go towards the Kuff parade.
09:32 And in the middle, there is the stabilizing line.
09:36 It is for the purpose of reversal and to stabilize the trains and to park them.
09:41 And you have told us earlier that you have provided the stabilizing facilities on both sides of the station.
09:49 Yes.
09:50 So, we have provided a provision that two trains can be parked at the same time at this station.
09:55 So, we have provided a provision to park one train at each end, at the north and south ends.
10:00 Sir, we saw that the metro that goes from Andheri to the top,
10:05 there were glass doors till half of the track.
10:12 But here, we can see that it is completely closed.
10:15 This door is completely closed.
10:18 So, is there any other provision for this?
10:22 Yes.
10:23 This is called the platform screen door.
10:26 And this is a different safety feature of the metro line 3.
10:31 You must have heard that there are some accidents on the metro track.
10:36 So, keeping all these things in mind, we have provided a provision of closed PSD.
10:41 The platform screen door will be closed.
10:45 It will only open when your train stops.
10:48 And simultaneously, this will also open along with the train door.
10:52 And as soon as the train door closes, this will also close.
10:56 This will avoid any incident or deliberate attempt.
11:02 So, it is synchronized.
11:04 Yes, it is synchronized with the train.
11:06 Apart from that, we have another facility that
11:12 the air conditioning load for the environmental control system is also reduced substantially.
11:21 So, this is our dual feature.
11:23 One is the safety feature and the other is that the air conditioning load is also reduced.
11:27 Sir, we have heard that different metro lines are going to come here at the same time as BKC.
11:33 And then it will pass ahead.
11:35 So, we are seeing here, you told about the station that it is a very big station.
11:40 And we can see that there are 8 escalators present here.
11:45 So, this is a provision for the different lines that are going to come.
11:49 So, you have heard correctly, there is another uniqueness of BKC station.
11:56 We are going to connect this with line 2.
12:00 Line 2 is basically in two parts, line 2A and line 2B.
12:05 So, altogether, this is a line from Dahesar to Mandalay.
12:09 We are going to connect this and BKC is an interchange station.
12:13 And the provision that we have kept is that we will do a paid-to-paid connectivity.
12:19 This means that once you enter the system, you do not have to leave the system again.
12:26 You will connect directly from our concourse to the line 2B concourse.
12:32 So, once you have taken the token, once you have entered the system,
12:36 you do not have to leave the system again.
12:39 You will not go out of the station, you will go from one platform to another.
12:46 When we talk about BKC, we also talk about the bullet train.
12:50 So, the bullet train is also going to pass through here.
12:53 So, will it connect with the metro line, will it be the same station or will it be a different provision?
12:59 So, the bullet train station, the high-speed rail station,
13:03 BKC station is almost an aerial distance of 1 km from here.
13:08 And for a distance of 1 km, we have kept a provision in our system,
13:13 a provision in the structure that a corridor can be built underground in the future
13:19 and we can connect the BKC station of the high-speed rail from that corridor.
13:25 So, we have kept a provision in that corner at that place on the concourse.
13:30 And when any authority wants to connect both, they can easily connect it.
13:36 So, the connectivity of the bullet train will also be done through the metro.
13:39 Yes, we have that provision.
13:41 The work of the metro, the first phase has been almost completed.
13:46 So, how much has been completed?
13:49 And now the talks are also going on that in December or in January,
13:54 that is, in the new year, Mumbai will get this metro as a gift.
13:59 So, tell us about that.
14:01 So, as you can see in the background, the work of the station is almost over.
14:07 And at the same time, we are preparing for the trials.
14:12 In fact, it takes some time in the trials, so we are preparing for the trials.
14:16 So, once the civil work will continue, there will be trials.
14:20 Once our internal trials are over, we will invite the authorities for the final check.
14:27 Once the approval of the authorities is received, then our line will also start.
14:31 So, I think that time is not far.
14:34 Okay, thank you very much.
14:36 You came to Ghost Mumbai in both these episodes.
14:40 And you told our readers everything in detail at all levels.
14:46 Thank you so much.
14:47 Thank you very much.
14:49 Thanks for giving me this opportunity to explain the entire Mumbai line 3 to people.
14:54 Thank you very much.
14:55 Thank you so much.
14:56 So, friends, the Mumbai metro line, which is going to Bhoogarbat,
15:00 the various things that are in it, the important things, the seriousness of it,
15:07 and many interesting and fun things related to it,
15:10 we understood all these in 4 different parts.
15:14 In the last part, we understood how the metro route going under the Meethi river was mapped,
15:21 and how the mining work was done.
15:24 In this part, we understood that for all the Mumbaikars,
15:27 it is a matter of pride that the BKC metro station is going to be one of the biggest stations in the world.
15:36 And we understood the various specialties of this station in all these parts.
15:43 In the next Mumbai episode, we will understand many more interesting and interesting things.
15:50 Until then, do watch all the Ghost of Mumbai episodes and share them with your friends.
15:57 Don't forget.
