Shame on the person, who did the paintwork! It was done in very careless way. Sorry to say :(

Do you mean that the painted surface is not smooth? Nearly all trams in Omsk are painted like this. It's the old paint not removed completely before applying the new one.

Yes, they did not remove old paint before painting new paint. As well, painting over rubber on windows. Sorry, I do not understand WHY doing so. I understand, that companies have no money for new trams. But, even old trams can at least be painted good :) Sorry to see!
