An XPT seen exiting the Bethungra Spiral, one of only two railway spirals in Australia. This spiral was built in the 1940s as a part of the line duplication process as rail traffic increased. The spiral also makes the grade a more train friendly grade of 1/66 for the up train services, which was previously a 1/40 grade with the single line (now the down). It is located near the 454km post from Sydney. British Railfans might recognise the distinctive lines of the XPT as being similar to the Class 43 HST - better known as the InterCity 125.
