Ballast Pit is located 135.340 kilometres from Mungar Junction. Sidings were provided to the Ballast Pit in the Burnett River and telephone connection with Maryborough and Mungar Junction.
The accommodation consisted of a loop siding 110 metres in the clear that ran parallel to the Main Line and fitted with a choke block with three Dead End Sidings off the Loop siding.
The No 1 Dead End siding was 680 metres long, No 2 Dead End siding was 300 metres long and the No 3 Dead End siding was 420 metres.
The Dead End sidings were on a steep gradient of approximately 1 in 30, and extreme care was taken when shunting the Ballast Pit sidings especially in wet weather.
