DPP #349, Picture 1, Namesti Republiky, Prague, CZ, 2006

I know a lot less about Prague's earlier 4-wheel trams than I do about their 8-wheel trams, other than that they were built mostly by CKD (as opposed to Tatra, CKD under contract with Tatra, or in recent years Skoda), at least after electrification, and many survived into the 1970s, and many if not most of those are still in service on the historic tram service, route #91 Stresovice-Vystaviste. They're also used for charters, as here with #349 at Namesti Republiky.
