Passengers have voiced their frustration with Sydney's train network, with Cityrail recording an increase in complaints.Railcorp's annual report for the last financial year has been released.
It reveals that more than 26,000 people were unhappy with the level of comfort and the convenience of the train network - 5,000 more than the previous 12 months.
Most complaints were about the lack of airconditioning on trains, however, changes to the timetable also sparked a flurry of phone calls and emails to Railcorp.
Timetable complaints alone rose 400 per cent while other complaints relate to staff and late trains.
But it was not all bad, feedback with compliments up 13 per cent.
The annual report also reveals a slight drop in the number of people catching a train.
Cityrail has blamed the GFC for the fall.
But the State Opposition says people are just fed up with poor service.
