You were lucky with the traffic. It can be quite busy there, although it has been reduced as a result of Corona. In any case a nice picture!

Thank you! I was also surprised and of course glad for the opportunity to make nice picture of 7900s, which are going to be retired in next years...

Don't worry, they are already undergoing another major overhaul which will allow them to remain with us for a number of years to come.
The 7700/7800 series are the next to disappear, but for this the space profile still needs to be adjusted here and there. Line 39 is almost completely finished: tests have recently been done with trams of the series 3000. Only the underground terminus Montgomery poses a problem, but this would be rebuilt in 2021.
Afterwards, the unsuccessful 2000 series will probably disappear: they cannot drive underground and are actually too small.
Perhaps not the whole 7900 series will be renovated, but like the 7700/7800 series, they will remain in place for many years to come.
