I think higher speeds can help efficiency. For example it can help catch up a train that has been delayed.

West European rail is very full, so rail use is carefully coordinated, since trains of vastly different speeds (e.g. ICE vs a regional train) use the same tracks. If an ICE is, say, 15 minutes late, they cannot just drive faster to catch up. The schedule went on, and at that point there may be a much slower regional or intercity train on the same trajectory. This is why ICE delays tend to cascade. It starts with a sh…

If it is the same as in Switzerland, the solution is in helping people get the health care they need. Most time I got annoying delays when I was living in Switzerland was because of a "personal accident" which 99% of the time meant someone had deliberately jumped in front of a train.

'ICE' here means Intercity Express [0] and not internal combustion engine. [0] https://en.wikipedia.org/wiki/Intercity_Express

And also not the organization currently force-relocating innocent civilians to detention camps. I wonder if the Germans will end up having to rename the train system at some point.

You know, now that I think about it there is a conspicuous absence of organizations with the initialism SS despite the letters being so common. Maybe they will!

Bike lanes reduce congestion. Do you prefer being slowed down by people riding bikes?

This looks technically correct but let’s exaggerate the speed up to drive my point. Let’s assume trains are 2x faster now than before. You can now either reduce the time and pack the schedule or use the extra “x” time for catching up when needed. Where does this logic break?

The 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.

While DB is obviously involved, this test train included cars from a new design that Siemens primarily is aiming at the export market (E.g. US Brightline West, various projects in Asia, ...).

> America seems to be suffering the same fate Not uniformly. New York's LIRR (90 to 95% [1]) and Metro-North (99% [2]) feature on-time rates that rival the Swiss (93% [3]).

You might want to look into what they define as being "late". > A commuter train is considered on-time by the LIRR if it arrives within 5 minutes and 59 seconds of its scheduled arrival time. The second source doesn't say, but let's assume it's the same as for LIRR, i.e. 6 minutes. It's also unfortunate that the SBB doesn't immediately tell us the metric, but I happen to know it's 3 minutes (more specifically 2 minut…

Is on time counted as time at every stop, or just the terminal. It’s easy to fake the terminal times with little impact by padding the timetable. Being on time at every station is far harder.

Not sure how you compare a small simple system like Lord which is pretty much one line with a few branches with an integrated multi-national system like the entire Swiss railway either

This article communicates what this is about very poorly, so I'm not surprised a lot of people are asking "what is so special about this train?". The answer is: Nothing. Many ICE trains have the capability to go that fast* - and some already surpassed these speeds on test tracks decades ago. It's really nothing special to make a train go these speeds. What this test was supposed to show is that the real track (not a…

I feel like the article is fairly clear

> DB und Siemens Mobility haben bei Testfahrten einen neuen Geschwindigkeitsrekord für die Strecke Erfurt–Leipzig/Halle erreicht

> Der ICE-S der DB Systemtechnik wird hauptsächlich für Test- und Messfahrten eingesetzt. Er dient dazu, neue Strecken zu testen, die Infrastruktur zu untersuchen und verschiedene Hochgeschwindigkeitsprüfungen durchzuführen

The latter paragraph explicitly states the point of this specific train is to test new routes and to analyze the infrastructure.

I think, like usual, it's a case of people reading the title and then going off to write a comment.

The Netherlands proved you can do bike lanes quite well, not every country has to be a nightmare for life quality like the US aspires to be.

You are talking policy, I'm talking material science.

Of what issue - the reliability of trains? It’s pretty high, db is a laughing stock.

A high speed pr stunt isn’t much interest sure.
