The venerable Łęgnowo suburban line with the best photo opportunities in the city looks especially authentic with the classic Konstal 803N tram. Thanks for the photos.

It is somewhat unusual to see trams on Line 9 on the Łęgnowo line in all of your photos, which was a supplementary peak hour service. Did Line 9 operate as often as Line 6 at the time?

I really can't remember this, sorry...
By the way, it is only a (small) selection of what I own and then photographed. I've more photos of the regular Konstal 805NA trams. I shared now the lesser-known 803N here, but this does give a false impression, as I photographed only 4 or 5 of them.
