The line is operated entirely by NSW TrainLink V sets.
As the electric overhead wiring ends at Lithgow, diesel-electric Endeavour railcars operate the services to and from Bathurst.

All electric Blue Mountains line services start and terminate from the intercity platforms (4-15) of Central (Sydney Terminal) station.
During the weekday off-peak, they operate hourly, alternating between services to Mount Victoria and Lithgow.
During the morning and afternoon peaks, some express services operate, together with short workings to Springwood and Katoomba.

There are two services each way from Bathurst to Central, known as the Bathurst bullet, mainly catering for commuters working in Sydney.
Two services run toward Central in the morning and return in the afternoon.
Two shuttle services operate from Lithgow to Bathurst in the early morning and return to Lithgow late at night.
Some of these diesel services operate to different times on Wednesdays to allow for the Indian Pacific.

Some off-peak electric interurban services on the line only consist of four carriages, with peak hour services usually consisting of eight carriages.
Regional diesel services on the line consist of two carriages.
