Emergency services took almost 90 minutes to rescue a woman on a mobility scooter who fell onto tracks at Parliament station.
Police, paramedics and firefighters were called to rescue the woman, aged in her 60s, who fell from platform 3 just before 1.30pm.
The Sunbury, Upfield and Craigieburn lines were running direct to Flinders Street instead of through the City Loop.
Werribee/Williamstown lines: Trains for these lines are now running direct to Flinders St (not via the City Loop) due to an MFB request.

A Public Transport Victoria spokesman said emergency services were controlling the site.
"Please listen for announcements, as some services may be altered at short notice," he said.
