Sorry, "pretty journal" was just a bad autocorrect I didn't spot. It was meant to say "pretty normal".
The problem with rail is the capacity issues affect the entire line. If one station has busy platforms and the rest are all quiet, you can't put additional trains on that line (unless it's a terminal station and there's a turning circle before that station and you are willing to run trains that don't go there). Also if one line shares fast and slow trains, that kills capacity.
One airport can share fast and slow planes, and capacity problems at one airport don't affect other airports.
I guess I'm writing mostly from the British perspective. My comment about fuel taxes paying for the roads is (or was) true for the UK.
Since privatisation at the start of the 1990s decades of decline in ridership turned around and now more people use the railways than ever. In the UK there are lines everywhere that are not only at capacity but drastically over-capacity, e.g. there's a train departing from Euston on a Friday night that carries more than 2x the number of people it was designed for. Despite that Crossrail - one of the biggest civil engineering projects in Europe - isn't even open yet, the country just committed to an even more eyewateringly expensive new rail line that won't be open for over a decade. Primarily justified on capacity grounds.
Heathrow expansion is also very expensive of course. But there's really only one airport in the entire country that has such severe capacity issues, and the expansion is difficult primarily because it's surrounded on all sides by urban development like motorways and villages that have to be demolished and relocated. In the case of the motorway, it's also carrying such large capacity that it can't actually be closed for extended periods, so it has to be moved whilst "live".
I think the USA has a different set of issues because the railways are used mostly for cargo rather than passengers. The large distances involved means air travel is the only feasible mode of transport for many routes, and Americans take internal flights all the time whereas for most Brits I know, internal travel is almost always car or train. Business people take internal flights, and even then only quite rarely. I've traveled Acela and indeed it also wasn't heavily used.
- eesmith 7y agoAhh. I was thinking that "journal" was either some new slang or a region term that I hadn't heard of. Thanks for the clarification. Regarding "kills capacity", aren't passing loops meant to help that exact scenario? https://en.wikipedia.org/wiki/Passing_loop https://en.wikipedia.org/wiki/Passing_loop has many details. At the very least, it's not as dire as you describe. I know little about the UK rail system -- or any country's rail system, for that matter. I do know your rail enthusiasts despise the Beeching Cuts, and that just saying that term is a hot button for some.
- thu2111 7y agoThere are plenty of ways to increase capacity on a railway line especially if you can build new rails, but at some point it just gets too difficult. The railways are surrounded on all sides, almost everywhere, by urban development. Homes and businesses have to be relocated, earthworks have to be done, and it all has to be broken into tiny pieces done in 4-5 hour spans in the middle of the night or over Christmas, because the railway is live and too economically important to shut down for long periods of time. Doing any kind of upgrades at all on a live line is horrifingly expensive and slow. That's why HS2 is a completely new railway. The UK has reached the limit of adding capacity to the West Coast Main Line; further upgrades are possible in theory but can't solve the fundamental issue of the same rails being shared by fast and slow trains. As for Beeching, it's not quite that simple. The roughly 25-35% of the country that's pretty left wing hate the Beeching cuts for the same reasons they hate all government cuts. Despite my negative view on trains above, I'm actually a train enthusiast. I love taking the train. I love reading about how they work. There was a story on HN some days ago where a rail engineer talked in detail about how the high-speed rail record was set, I absolutely loved reading about it. My girlfriend had to tear me away from the screen. And I've often wondered about how to really scale up the railways in a big way. In a way, railways are kind of the ultimate nerd dream. An ideal railway is a huge, smoothly operating and very safe high performance machine, entirely coordinated by engineers and planners. I think perhaps that's why it's such a political hot-button issue: a nationalised railway represents a very tangible instance of massive state planning and control. Decentralising it is difficult for various logistical and technical reasons, not only the politics of it. Despite that the Beeching cuts have never been rolled back, even under the 3 terms of Labour government. Many of those lines made no sense, especially in the context of continually declining ridership and the ever rising traffic on the roads. It'd have been a very irrational government that continued ploughing money into rail instead of building motorways given the expressed preferences of the population at the time. For unknown reasons that are still debated today (but which align perfectly with privatisation), the decades-long decline in train usage reversed and so now new lines are needed again. But they're different routes to the ones closed by Beeching. Those were mostly small rural lines.
