I agree with your point on DSJ. DSJ has space for 1 or 2 more platforms maximum. The bigger problem will be the approach roads to the station which are too narrow to accommodate too many vehicles. The parking space is to small as well, which can cater to a load of vehicles for the passengers of 1 popular train at a time only. It is better with tourist trains and special trains only. DSJ located in a peaceful govt neighborhood and let it be a peaceful place.
On a lighter note, the locals learn driving at the parking lot of the station. :P
