Dear Deutsche Bahn – Thanks for the Involuntary Deep Work Session
A stationary ICE somewhere between Hamburg and Bamberg. No signal, no progress — and my most productive morning of the week. Why disruptions are sometimes the best workspace you'd never book.

Bildung & Story
- Zwang schlägt Absicht: Wer nicht weiterkommt, muss sich mit dem beschäftigen, was da ist — und das ist oft die produktivste Konstellation überhaupt.
- Der Zug ist kein Transportmittel — er ist ein unfreiwilliger Deep Work Raum, ohne Kalender, ohne Büro-Interruptions, ohne Ausreden.
- Claude läuft überall: KI macht Wissensarbeit ortsneutral — das Büro ist ein Mindset, kein Ort.
- Constraint beats intention: When you can't move forward externally, you're forced to engage with what's right in front of you — and that's often the most productive state of all.
- The train is not a transport vehicle — it's an involuntary deep work space, free of calendar, office interruptions, and excuses.
- Claude runs everywhere: AI makes knowledge work location-neutral — the office is a mindset, not a place.
- Passive consumption vs. active creation: The car gives you podcasts. The train gives you thinking space. The difference is smaller than you think — but the results are not.
Deep Work in Transit is the ability to convert waiting and travel time into concentrated, cognitively demanding work — not through discipline alone, but through the structural enforcement of focus that travel situations inevitably bring. It's not a technique; it's a mindset. Anyone who understands that a stationary train is not a moment of loss but a moment of gain uses travel time as a natural deep work container — undisturbed, free from meeting invasions, without the social pressure of the office.
The Train as an Involuntary Deep Work Space
It started early that morning, things beginning to unravel. Two S-Bahn trains cancelled, no replacement in sight. Then a taxi — stuck in traffic. Then the connecting train at the main station, caught by seconds. The ICE departs. Five minutes of movement. Then: standstill. An overhead wire fault. Somewhere on the open track between Hamburg and Bamberg.
In moments like these, one question surfaces: Should I have taken the car? The honest answer is no — and not for romantic reasons. In the car I'd have been stuck in traffic too. The A7 on a Tuesday morning is no leisure park. The difference would have been: in the car, I'd have listened to podcasts. Passive consumption. Information intake without processing.
On the ICE, by contrast: laptop on the fold-down table, Claude running, ideas flowing. The external standstill forced internal movement. That sounds like a pious management quote, but it's psychology. Human beings tend to fill gaps — and when scrolling through LinkedIn or checking Slack isn't an option, they land on what actually matters.
Why Disruptions Enforce Focus
In everyday office life, every knowledge worker battles an invisible adversary: permanent availability. The next Slack ping is three seconds away. A colleague drops by. The calendar fragments every hour. The result is what psychologists call cognitive fragmentation — work that never goes deep enough because it's always interrupted before the brain genuinely enters a flow state.
In the stationary ICE, this problem doesn't exist. No meeting can be spontaneously called. No door handle can be pressed down. And — crucially — no guilty conscience for being somewhere else you should be. You are where you are. There is nothing to miss. That is a rare form of psychological freedom.
"The train is not a transport vehicle. It's an involuntary deep work space."
— Tom Adebahr, irgendwo zwischen Hamburg und BambergWhy Waiting Used to Mean Loss — and Now Means Gain
There was a time — not long ago — when a forgotten laptop was the ultimate excuse. "I couldn't work on the go." No network, no device, no argument. Waiting time was idle time. Train delays were frustrating theft of hours.
Then came the smartphone era, and waiting became passive consumption. Podcasts. Netflix. Endless scrolling. That was progress over doing nothing — but not a qualitative leap. You receive, but you don't create. You listen, but you don't think.
With AI — specifically, with Claude — that changes fundamentally. Now you can not only consume but create. Develop ideas, write articles, think through strategies, elaborate concepts. Claude is the co-pilot who's always there — without needing a seat of his own. This post, which ultimately reached 3,431 impressions on LinkedIn, was written on a stationary track. In real time. As a flow of thought, not a carefully planned editorial project.
The Difference Between Passive and Active
Podcasts are wonderful. I listen to them myself — on the treadmill, while cooking, in moments when my hands are busy but my head is free. But a podcast on the train is missed potential. Because on the train, both hands and head are free. That's a rare combination. Don't waste it on consumption.
The concrete switch is simpler than you'd think. It doesn't take special discipline. It takes only a decision made once — and then consistently maintained: train journey = work time. Not social media time. Not podcast time. Work time. And with Claude as a partner, that work time becomes one of the most valuable hours of your day.
The Deep Work Advantage: What You Do While Others Wait
In his book Deep Work, Cal Newport formulated a thesis that sounds banal at first glance and radical at second: The ability to concentrate deeply is becoming rare — and simultaneously ever more valuable. Those who master it have a structural advantage that manifests in results that others simply cannot produce.
What Newport didn't yet have in the book: AI as an amplifier of that ability. Today, deep work in transit no longer just means "laptop open and write." It means: laptop open, Claude as a thinking partner, and starting a feedback loop that wouldn't be possible in the office in this form. You voice an idea, Claude structures it. You type a thought, Claude sharpens it. You sketch an argument, Claude challenges it. That is collaborative thinking at a level that previously required a team of people.
Concrete Tactics for Productive Train Journeys
The crucial point: you can apply these tactics immediately. No investment. No onboarding phase. Just a changed attitude toward time you're spending anyway. And with Claude as a permanent co-pilot, the leap from passivity to productivity is smaller than ever.
I Am the Office
There's a sentence that appears more than once in this article, because it carries more than it seems to at first glance: I am the office. What does that actually mean — beyond the pleasing LinkedIn ring of it?
It means: Productivity is not tied to a place. In 2026 that sounds self-evident — after three years of remote discourse, after Zoom burnout, after a hundred "work from anywhere" articles. And yet most leaders still act as if the office is the only legitimate place for serious work. The ICE fold-down table isn't a real desk. The café WiFi isn't secure enough. The train journey is lost time.
This mindset is a relic. And with AI it becomes even more outdated. In the past the argument may have had merit: without access to your systems, without the local network, without your second monitor, you were genuinely constrained. Today, Claude runs everywhere. Notion syncs. HubSpot is cloud-native. Your entire operational stack is browser-based or offline-capable.
What This Means for Modern Leadership
Leaders who have understood this have a different rhythm. They don't protect office time — they protect thinking time. It doesn't matter whether that thinking time happens at a desk, on a train, or at a kitchen table. What counts is the quality of concentration and the quality of the result. Location-neutral leadership doesn't mean always being on the move. It means not using place as an excuse for a lack of productivity.
This also has a consequence for teams. Leaders who are themselves location-neutrally productive build teams that can do the same. They evaluate output, not presence. They ask about results, not hours logged on a company machine. And they send the implicit signal: Your best thinking can happen anywhere. Let it.
That morning between Hamburg and Bamberg made something clear to me: I don't need perfect conditions to work well. I need the decision to do it. Everything else — the stationary train, the missing signal, the overhead wire fault — is background noise. Claude runs. The mind runs. That's enough.
