Today started out on EC 171 to Prague. The Train was originally suppose to head south out of Berlin Hauptbahnhof to Berlin Sudkreuz, however when we arrived at the station the train boards said it was boarding at platform 12 instead of platform 1 and one announcement was made to this fact. The equipment on the train was Czech, with 2 DB locomotives pulling it. The 1st class cars were nice with leather seats in a 2+1 configuration, LCD information displays and other modern amenities. The cars themselves were built in 2006 by Siemens and they looked recently renovated at that. Due to the reroute, we never went to Sudkreuz, but instead out of berlin via Berlin Ostbhanhof. The line segments we traveled on were SLOW, we lost probably 40 minutes on this reroute and arrived at Dresden late. At Dresent the DB power was switched out for CZ power, which took almost a half hour with some technical difficulties. The rest of the trip to Praha Hadrazi Holesovice was fast and pleasant. At Praha Hadrazi Holesovice we took a tram to Vystaviste Holesovice where we caught the 91 Historical tram line to the tram museum. A beautiful tram and trailer set arrived shortly after we did and after a short wait we were on our way. The 91 historical tram route passes through downtown area on its way to the tram museum. When we arrived at the tram museum, they have a VERY large collection of equipment from the early 1900s to one of its newest pieces, a bus acquired in 2004. A lot of it has been completely rebuilt and restored from all sorts of conditions and is in very nice shape. They had a vintage T1, T2, and T3 streetcar set on display, several other older trams, some Maintenance of Way equipment, a vintage trolley coach, a multi section tram from 1990 as well several buses including an Ikarus artic. Once we were done at the Museum, we took a 25 line tram, to connect with the 18 to connect with the 22 line at Malovanka station. The 22 line took us downtown, where we walked through downtown taking pictures of the trams passing every few minutes, to the main train station at Hlavni nadrazi. The Main train station even after a modernization and addition of shops, still has a bit of a 1960s communist era feel. very dark, very narrow passages, and on top of it, they don't post train information at least for our train the EC 170 until 5 minutes prior to departure. This was not of much concern however as the train was not even on the platform yet. The ride back was pleasant until we got onto DB tracks and the detour, where about an hour was lost making our way back into berlin. We had to stop once in a siding to let another train pass, and made our way very slowly back into berlin.
