CC20151 with CC20152 leads 12 loaded-tanker wagons from Maos to Tegal, passing in the Karangsari Bridge, where the double track project (Purwokerto-Patuguran) is working. This trainset must be drawn two locomotives as it passed the mountain path is uphill. And now,this double track project has been completed and is already used, so that makes travel time more quickly. I like it.
