I had a chance to take a German DB ICE4 from Nurnberg to Berlin this past weekend.
Route is a mix of high speed and conventional lines. Train originated in Munchen.
From Nurnberg we stopped at Bamberg, Erfurt, Leipzig, Bitterfeld, and Berlin. These stops were typical. There were no nonstops between Nurnberg and Berlin.
Distance was 440k/275m. Time was just over 4 hours. That’s only 110k/70m per hr. Not very impressive. The steam 4-6-4 Class F7 Hiawatha of the Milwaukee Road in 1940 did CHI-LaCrosse of 281mi in 4 hours with a similar number of stops. The TGV does Paris to Bordeaux nonstop in 2 hours covering 500k/310m.
I noticed that while the TGV bypass the intermediate cities full speed (with spurs for trains stopping) the ICE doesn’t seem to have bypasses and they stop at most or maybe all cities in between running over suburban tracks in the city portions.
Note I’ll round all conversions to miles to the nearest 5.
The segment to Bamberg was conventional line with a MAS of 160k/100m per hr. The train was late arriving from Munchen by about 20 minutes. So naturally leaving Nurnberg we immediately got stopped by signals as we were out of our slot. But the dispatchers did a good job and we did not lose more than a few minutes more the rest of the way.
From Bamberg to Erfurt the MAS is 300k/185m per hr. But the ICE4s can only go 250-265m/155-165m per hr depending on gearing. I clocked a high of 260k/160m per hr.
From Erfurt to Leipzig MAS is also 300k/185m per hr. Again I clocked a 260k/160m high.
From Leipzig to Bitterfeld MAS is 200k/125m per hr. I noted that at 200k the train hunts a bit. Not unnerving but a noticeable yet gentle rythmic sway. At 260k it did not hunt. Ride at all speeds is smooth and quiet. Seats comfortable. Wide and good pitch. Like a domestic US first class airline seat. On DB I rode 2nd class.
Bitterfeld to Berlin has two possible routes. A more direct and faster routing is 200k/125m per hr. via Wittenberg. We took the longer and slower routing via Dessau with a MAS of 160k/100m per hr. Why I have no idea? Maybe track work? Although we didn’t seem to lose time so maybe that’s its normal routing?
One difference is that the line via Wittenberg arrives in Berlin from the south naturally while the round about route via Dessau arrives in Berlin from the North.
One thing any train enthusiast should see in Berlin is the Hauptbanhof (main train station). Very new (about 2000) but the most impressive train station I’ve ever seen (although I’ve not seen the train stations in China that I hear are also spectacular).
Here are a few pics of the Berlin Hbf including a model that shows the scale of the place.
