On a coal January day in 2016, JS8190 storms past her sister, JS8225, leading a heavy coal train upgrade at Sandaoling. Just minutes before, these two steam locomotives were working as a team, when JS8225 lent a hand to start JS8190's overloaded train. Now, much of the excitement was over as JS8225 patiently waits for JS8190's train to clear the junction. As soon as the signals turn to green, JS8225 would back down to the loader for another load of coal.
