Train stops between Berlin and Warsaw

(Just to add: We've got five days in Warsaw and then five days in Krakow, so the focus of this post is only on the three nights in between Berlin and Warsaw)

Poznań city centre/old town is a big bulding site at the moment so not looking its best. The renovation works are expected to continue until the end of the year.

Skip Poznan and go to Gdansk instead.

Have you looked into what stops are practical traveling from Berlin to Warsaw?

From my understating Berlin to Gdansk (and other parts of Poland?) by train is a headache right now due to construction around Frankfurt an der Oder, so a part of this route is serviced by a bus. https://community.ricksteves.com/travel-forum/germany/help-berlin-to-gdansk-tomorrow

I think Berlin to Wroclaw might work better? I'd pass on Poznan or Lodz and spend 3 nights in Wroclaw.

Thanks to all for your feedback so far.

Carlos - from what I've been reading, the direct train from Berlin to Gdansk would be running again before the summer begins (I believe it was mentioned that there would be restrictions until 21 April), so my assumption would be that there would be no issues in July. Please correct me if I interpreted that info the wrong way.

I think that all of your ideas are good, but if you have any doubt, you can modify it for example in one of these ways:

1. one night in Poznań and two nights in Gdańsk (both of them are connected with Solidarność, Poznań very earlier than Gdańsk; you can look for the monument of Poznań 1956 near the Adam Mickiewicz University rectorate, the Music University and the Kaiser castle in the center of Poznań),
2. two nights in Poznań and one night in Łowicz (with Polish folklore, you can also see the cathedral in its center and two museums near Łowicz - in Maurzyce and Sromów, but take also Arkadia and Nieborów into consideration; TAXI is on the main market square in Łowicz - near its southern wall),
3. one night in Poznań, one night in Łęczyca (with the famous settlement and church from the Middle Ages in Tum near Łęczyca, TAXI is on Szpitalna street, near the church, just one minute from the old market square with the town hall, so to the west, the opposite direction than from the market square to the castle) and one night in Łódź.

Thanks for the response, plikows

We ended up deciding to do the three nights in Gdansk plan and have booked a direct train from Berlin to Gdansk, leaving next week. Our flight to Berlin is tomorrow and we'll stay for nine nights with day trips planned and then will spend 3 nights in Gdansk (including a half day trip to Sopot and taking in a couple of museums in Gdansk), then five in Warsaw and five in Krakow beforen moving on further south/west.

Thanks! You can think about other options next time. I have added information about Taxi in Łowicz to my previous description. As you have long time in Berlin, you can visit Szczecin (where I live), travelling by train (Deutsche Bahn). You can read about Szczecin on https://www.travellerspoint.com/guide/Szczecin/. Other options are among others Greifswald and Stralsund, also by DB train.
