The government seems to be mulling the option of running commuter rail to KIAL. It would make complete sense to run suburban trains to KIAL because of the low costs involved. The government needs to ensure that trains are run to the airport after the construction of a railway station at the Trumpet Interchange. A few trains with AC coaches could also help. The average Bangalorean seems to have a negative image of CRS. Therefore well maintained trains could definitely help in terms of an image makeover and make it popular. The airport needs to be linked through the two different routes i.e. via Yeshwanthpur and Byappanhalli so that people make use of CRS and the trains do not run empty.
Efforts also need to be made to run local trains originating from Yelahanka and ending at Doddaballapur and Kolar.The current train running from SBC to Kolar takes a minimum of 4 hours to travel. Trains could be run from Yelahanka to Kolar via the newly revived Kolar to Chikkaballapur rail line. The towns of Kolar, Chikkaballapur and Doddaballapur have quite a few industrial estates and workers and staff living in North Bangalore and working in these estates could benefit immensely if Yelahanka is used as a starting point for suburban trains. Yelahanka could be connected to YPR, SBC and Byappanhalli through EMUs to ensure speedy transportation to Yelahanka station. The Yeshwanthpur to Yelahanka section is currently seeing track doubling. Railways are keen to develop Yelahanka as a major hub for outstation travel. It is imperative that CRS is implemented on this route if SWR wants to run outstation trains originating from Yelahanka. This is in light of the fact that Yelahanka is located at the northern end of the city and not near the city centre.
