This is rather my own experience. Reaching Berlin from Legnica when I couldn't get my train ticket to Berlin from Wroclaw.
Berlin is a must see when you are in Germany & especially in Legnica, splash your way to Berlin !
Also from Legnica, there would 2 trains a day to Poland's capital Warsaw.
Also, a train per day to some destinations in Germany like Frankfurt, Dresden & Leipzig.
Anyhow, I reached Berlin !MY BERLIN PAGE
Well, Legnica is near Wroclaw, about 75 km. It is only a short train ride away !
Wroclaw is a beautiful city in Poland ! Filled with great sights & the most beautiful Town Square that I have been to in Poland ! When you are in Wroclaw, you must visit Legnica. If you happen to be in Legnica entering from Germany, please make sure you reach your way to Wrcoalw !MY WROCLAW PAGE
