One of the most remarkable sights of the trip, unfortunately not captured photographically, was DF4DD 0288 producing billowing clouds of steam as it emerged from the shed into the cold morning air on 22 November 2016. By the time the diesel had been to Meitian to collect some empties the effect was fading but the loco was still steaming gently on the return to Wujiu.
Condensation must have built up inside the loco while it was in the shed with SY 1225 and, as the engine warmed up, the water evaporated again and was expelled by the cooling fans, creating the steam cloud.
