Commuters using the Sunbury train line will have a bit more breathing space by the end of the month, with the addition of 10 new weekday peak time services on the way.

An extra morning and evening peak service has been added to the Monday to Friday timetable, which will begin from August 27.

Public Transport Victoria spokesperson Jake McLaughlan said the new services would help reduce the strain on peak hour services.

“Starting August 27, Sunbury line passengers will benefit from 10 more peak services every week via the city loop as part of a new Metro timetable, providing capacity for an extra 9000 trips every week,” he said.

The most recent passenger load survey on the Sunbury line showed 46.5 per cent of morning peak services were crowded above the acceptable benchmark, while 16.7 per cent of evening peak services were also overcrowded.

The new morning peak service will depart Sunbury at 6.48am and go via the city loop, while the new evening peak service will leave the city at 4.30pm, also via the city loop.

Four Sunbury line services will now run direct to Flinders Street via Southern Cross during the morning peak, removing the need to change trains or travel round the loop.

The timings of buses that connect with trains – route 400 from Sunshine and 460 from Watergardens – will be adjusted to reflect the new train timetable.
