Our friend Paul, who I went to Cologne with back in 2015 to photograph trains (see here) often comes to Germany to take photos of trains. A lot. Not just Germany but elsewhere in Europe too, moreso than he ever does in the UK. One of his jaunts brought him to Berlin where Sasha and I caught up with him in the evening for dinner and a few drinks; he headed off in Germany for a couple of days afterwards but ended up coming back to Berlin on the Saturday, to go to a loco shed Open Day at one of the yards. This was in a place called Seddin, just south of Berlin and not too far from Potsdam; and there was only the barest information about it online. However we both decided to catch up and head out to it - Sasha wisely opting not to come out.
That will do, because the rest are much of a muchness. Was fun, and probably the last opportunity I'll get to do this in Germany before leaving!
