You need connection,.you can demand a train... Pitlines don't solve the problem if there's no will to start a train sir. Asking for an extension which is easier, demand of new train takes some efforts, MP of those regions should ask. How many train did Guntur get after a pitline? Only Rayagada express was extended to free up bza. No relation here between infra and trains, if there is will some how they will arrange.
