Class M5c number 772 assembles her train at Peradiniya Oil terminal prior to departing with the empties to Colombo Docks in Sri Lanka.
Dedicated freight flows are few and far between in Sri Lanka. When i found out about this working i decided it was worth staying out late for.
The M5 class were built by Hitachi in Japan during 1979 the c suffix denotes she has been re-engined with a 1150hp Caterpiller 3516 DITA.
