Berlin's brand new fleet of Solaris Urbino 18 electric officially entered service on 27/08. A day later I was lucky enough to witness bus 5420 being charged at the terminus. While the entire fleet of 17 vehicles has been delivered and is scheduled to take over operation of line 200, only a handfull were to be seen on 28/08.

5 busses?

In a WhatsApp group there was an information of 2 or 3 busses only

I saw 3 myself (5420, 5428 and a third whose number I couldn't identify). There might have been more, so I didn't want to make a definitive statement that it's only three. 'A few' might have been better wording. There were a bunch of photographers though so maybe more pictures will show up over time.

Thanks :).

27-08-2020: 5420, 5428 and 5431!

Danke, Martin :).
