'ICE' here means Intercity Express [0] and not internal combustion engine. [0] https://en.wikipedia.org/wiki/Intercity_Express
Nowadays, it also means balaclavaed, secretive, lawless, paramilitary disappearance "police".

Yes but it’s a strictly better situation to be in although your point is valid.
Do you imply that trains would normally run slower than what they can safely achieve?
With clock face scheduling (like in CH and planned for Germany) they very much do since schedules are optimized to align with periodicity.
On some Swiss lines it's fairly common to have trains recover their delay at departure (which also avoids cascading impact).

#43The ICEs are already plenty fast, the issue is they share rail with the much slower and less reliable RBs. Any delay cascades and you can't just make ICEs go faster to catch up.
On a €/(avg. ICE speed) basis likely makes more sense to invest directly in RB.

#45What is special about this train? There are trains that already surpass this speed.

#46I fear that the general public in Germany will not be praising this achievement. The once efficient and punctional trains in Germany have deteriorated severely in the past years due to lots of delayed maintenance causing lots of delays and even regular cancelations of trains. Also the road infrastructure is suffering from delayed maintenance.
Agreed, nowadays I have to schedule train exchanges to have at least 30 m between them, and even so, I managed to miss connections.
DB is doing their best work for having people reaching out for cars.
While you might get stuck in traffic on the motorway, there are usually workarounds as soon as you get the next exit point, while being stuck on an train stopped in the middle of nowehere with a full train excedding passanger capacity because "pick random excuse", and reservations being optional, isn't really motivating to keep traveling by train.

Interesting; America seems to be suffering the same fate. It takes municipalities years to fix highways. The main highway running through Silicon Valley, 101, has been under construction for more than a decade and is in dire need of improvement. It seems the network of roads built in the 40s, 50s and 60s just can no longer be done efficiently.
> It seems the network of roads built in the 40s, 50s and 60s just can no longer be done efficiently. Of course they can, we have not lost that capability. It's not a matter of efficiency but effectivity. Road constructions of the 1960s are not effective for 21st century traffic demands. Today's level of traffic far exceeds the anticipated level of traffic at the time of construction. Germany sees this all the time,…

Citation needed.
As I see it, the US is still riding on the coattails of 1960-s road construction. We should be doing more of it, in fact, not sabotaging it with bike lanes and road diets.

#48Amdahl's law in effect - which is the reason trains in Germany top out at 300 and most at 250.
There's another factor in HSR speeds: track degradation and maintenance. If you run the trains faster, they cause more wear to the tracks and require more frequent maintenance, and also tolerances on the tracks need to be kept tighter. Germany already seems to have trouble doing maintenance on time, so running trains faster would make this worse.
Yes, the German rail services prefer to build huge new trains stations instead of better tracks. We're waiting for 120->160kmh for years now, always promised, always moved to the future.
And probably the tear is bigger on curvy lines which most lines in Germany are, compared to e.g. China.

Exactly this. The only people who will care are hardcore train people, and even then everyone is so crushingly disappointed with DB I doubt they mind much. I mean even at 405 km/h the train will STILL be an hour late.

Yea. Who cares if you can hit 405 km/h if you are just going to get stuck behind a train carrying goods for 2 hours unable to move.
