SWR is planning to introduce the double decker Train between Bangalore to Mysore once the coaches are made available from Rail Coach Factory (RCF) in Kapurthala to increase the passenger capacity.

Air-conditioned double-decker coach are running on trials on the Delhi-Moradabad section a few months ago

This should help passenger travelling between Mysore to Bangalore and catching flight at  BIAL, by extending these trains upto  BIAL. Trumpet Loop / Terminal of BIAL building.

Praja.in members travelled by train and proved that the trains can be cheaper and faster also. Sop why not we consider the existing options and link with BMTC buses to the IT sector areas in the city? Just a list of them: * The stations which are very well connected with BMTC buses are Krishnarajapuram,Carmelram and whitefield stations. The are closer to the IT sectors also.

1. Krishnarajapuram Junction: It has the bus stop attached to it on the outer ring road side. almost all trains bound south stop at this station. BMTC buses connect well to:

a) ITPL: 304,306,319,600 series buses

b)Mahadevapura: 500A,500C,500D,500N,500L,501,501B,502A,C-1,BIAS-8,BIAS-8A

c)Bellandur: Same as Mahadevapira except 502A

Trains from Bangalore city:

Lalbagh Express at 6:30AM Marikuppam passenger at 7AM Chennai Express at 8AM Chennai Passenger at 9:20 Bangarpet passenger at 10 Good parking facility available at city station/cantt station.

People prefer own transport mainly because they can travel directly by the shortest route non-stop to the school/college/workspot and back.To use public transport, one has to walk in the hot sun to the nearest bus stop, wait for the correct bus, somehow manage to get in, get down and walk again.some people have to take more than one bus.Because of the crazy one way maze, one has to walk to a different bus stop for the return journey.

It is certainly possible to provide a facility almost like own transport.Presently, sharing transport is limited to it/bpo computer savvy sector.But there are lots of other people who are not computer savvy, who do not have the time to log on to a computer ,etc (the bottom of the pyramid, to quote management guru c k prahlad) who would gladly join to form a transport pool.There may be so many people in an apartment complex traveling daily to the same place and back at the same time.They would probably be surprised to see familiar faces in the group and think "why didn't WE think of this ?"

The Bangalore Metropolitan Transport Corporation (BMTC) will be introducing three routes called K1, K2 and K3.

The route K1 will connect St John’s Hospital, Sinivagilu, Domlur, Indiranagar Police Station, Ulsoor, Trinity Circle, Mayo Hall, Shivajinagar and adjoining places.

The K2 route passes through Hebbal, Devasandra, M S Ramaiah Hospital, Yeshwanthpur, ISKCON temple and adjoining roads.

K3 connects Basaveshwara bus stand, Vijayanagar MCTC, Sirsi Circle, Chamarajpet, North Road, Basavanagudi, Shanthi Talkies and adjoining roads.

A release from BMTC said that buses along these routes will be made available at a gap of 15 minutes each between 6 am to 11.15 pm.

Here they should have extended K1 upto Cantonment Station.  Also integrating with METRO stations should have been taken care as many places, these buses will be playing close the METRO stations enroot.
