The long-awaited, second composition of the Underground Electric Car No.1 has been completed (it was supposed to be completed by late 2020). There are a few differences compared to the first composition: — it now has air conditioning, instead of powered ventilation — the orange bulbs on the top of the front mask now stick out slightly — the seats have slightly different colour — the television is now placed in the center of the car — most importantly, it does not use BVG Type D carts.

The metro set on the left is the first composition.
