Tourist tram 1193 of Den Haag. This is a so called PCC tram and it is now owned by Haags Openbaar Vervoer Museum (HOVM). It operates as a touristic sightseeing tram, starting from Kerkplein in Den Haag, then following the tram no.1 route to Scheveningen Noorderstrand seaside and then following the tramlines 11 and 16 routes back to Kerkplein. The tram is a PCC tram. PCC stands for President's Conference Committee. These are American trams dating back to the times right after second world war when most of Europe was in ruins. USA tried to help their European allies by the so called Marschall aid program and as a part of this programme also Netherlands received all kinds of help and materials including these trams. Most of the PCC trams were built in Belgium under US licence, but some were built elsewhere as well, for example in Sweden. A part of the trams and their components were sent directly from the US. The city of Den Haag received over 230 PCC trams and the last ones were actually made as late as in the 1970s just using the old US licences. This tram is from the third series of PCC trams which dates back to 1957-58. The trams of that series were built in Belgium at La Brugeoise and ACEC. The trams of this series were renovated during 1974-1980 and during that renovation they for example received new and more modern doors.
