It is also serviced by NSW TrainLink Xplorer long-distance services from Sydney to Canberra and Griffith.[8] This is a request stop for this service (except for Sydney-bound Canberra/Griffith Xplorer on Thursdays and Sundays), so the trains stop only if passengers booked to board/alight here.

Heritage listing
Mittagong is an important early site with significant railway buildings. The location of the station near the centre of the town gives it a civic importance. Of particular interest is the refreshment room which was used only for a short period until replaced by the refreshment room at Moss Vale because the Governor who alighted at Moss Vale for his country residence did not want to be kept waiting at Mittagong while refreshments were taken. The station complex in particular is of high significance with an early railway building (1867) surviving in the group.[4]
