Simply raise MST by 10 and you may see riots. MST is calculated on ordinary passenger fare, and most of these 25k people travel by M/E or higher and not DEMU and proposed MEMU. Start a monthly increase of 5 for MST to match with at least 30, then 40 journeys per month. Many of those use the facility to travel multiple times everyday, mostly traders or their agents/employees. No poor people will be affected by a hike of 5 in their monthly bill.
