Daily commuters across Kolkata are set for a major convenience boost as Metro Railway Kolkata announced a significant expansion in train services on both the Blue Line (North-South) and Green Line (East-West). Starting July 27 on an experimental basis, first trains will roll out earlier in the morning, and last services will run later into the night.

The revised schedule addresses long-standing passenger requests for extended operational hours, catering to early-morning travellers, shift workers, and late-night commuters.

Both primary corridors will move to unified early-morning and late-night hours:
First train: 6 am
Blue Line: advanced from 6.50 am (50 minutes earlier)
Green Line: advanced from 6.39 am (39 minutes earlier).

Last Train: 10.30 pm
Blue Line: Extended from 9.44 pm (46 minutes later)
Green Line: Extended from 10.05 pm (25 minutes later)

On Sundays, train operations across both lines will run continuously from 9 am to 10.30 pm.

Alongside extended hours, Metro Railway is scaling up total trips to lower waiting times during peak and non-peak hours.

On Sundays, train operations across both lines will run continuously from 9 am to 10.30 pm.

Alongside extended hours, Metro Railway is scaling up overall daily trips to lower waiting times during peak and non-peak hours. On the Blue Line, weekday services (Monday through Friday) will increase from 260 to 272 trains per day. Saturday operations will see a similar boost from 246 to 258 trains, while Sunday services will rise from 152 to 158 trips.

The Green Line will also experience a notable frequency boost across all days. Weekday trips will expand from 228 to 236 services daily, and Saturday schedules will expand from 204 to 212 runs. On Sundays, the Green Line will operate 111 services instead of the previous 108.

Metro authorities stated these experimental additions aim to streamline urban transit, expand suburban connectivity, and provide safe, reliable travel for late-night and early-morning passengers.
