This is the issue in Kerala where there are small small towns after every 25-30 km. Every passenger group of a station wants a particular train to have stops at their stations,thus resulting in lesser speed. In the last 1 year, Chalakudi,Mahe and Tanur have got added. Also heard that people were demanding it to be halted at Angamali and passenger associations in ernakulam side are urging railway authorities to consider giving halts for sme popular trains at edapally !!!!. Dont know where this is heading to? Just have a look at some of the long distance superfast trains running inside kerala. Once they are out of kerala so little stops!!
