тут фото явно не 2001г.
автобусы с гаражными номерами 51** в ленинском появлись осенью 2004 после скандального закрытия филиала на троицком тракте.

2 facts:

1. My collection of photos is very extensive and my own photos have been digitally indexed since 1998. All photos are written down on an Excel file, with all the details, including the number(s) of the vehicle(s), the line number, the street, the date and the negative number. This is done as quickly as possible (when returning home), otherwise details may be lost. These are analogue shots: the details were then noted down on paper and entered in an Excel file when I was at home. If not, it would be impossible for me to locate the right places again or to give the number of the second vehicle (where applicable). Or do you think I can really remember the name of the street after 20 years?

2. The overall rating of your comments is negative.

I know nothing about buses, and certainly not about Chelyabinsk. Indeed, I took the picture (and posted it here) for the combination of bus and tram. Of course, it is also about the time frame and the whole picture. The bus is of course off topic for this site and most visitors or users here are electric transport enthusiasts. Again: the purpose of this photo is to show what it looked like then. Details about buses and buses are better discussed on busphoto or a similar site.

If necessary: the date is correct. If you do some research yourself, you can see who was in the city on the same day. Hint: look at the photos of the 2001, taken on the same day.
