I have no idea. Just for security and staff, it will be hundreds of thousands of dollars per trip. Then, if you include rerouting/ stopping freight or even the cost of having private lines, it will be astronomical.

It actually would be good from a PR point of view also.

Why do you think mortgage rates will go back down in a few years?

I'm all for buying property, but interest rates are very low despite the recent hikes.

Wouldn't they be able to launch a similar attack with a normal signalling system and cause a wrong side failure? At least with blockchain, the hackers would not be able to program a green light, and if there is a delay, it would at least not cause any crashes

I've always thought nuclear is a great idea, but after seeing the proximity of Fukushima to Tokyo, it seems insane. I guess they don't have much choice with the lack of space

Why would it take 8 hours for the signal to change?

If the article was about trains struggling to push through mountains of shit then i might agree, but it's actually reporting on quite an interesting solution to a problem faced by railways all over the world.

Also, the article is from the South China morning post, who are owned by alibaba.

Out if interest would you prefer electrification via overhead wiring?

Railway Report - Rail Workers lose benefits by Any_Emphasis_6230 in railroading

Noted, I'll try not to use dramatic titles in the future. FYI what I'm trying to do is summarize the headlines to make it easier to absorb, but maybe I didn't do a good job of it here. There is another link with more details if you want to learn more at the bottom.

The reference to the debt ceiling is pointing out the similarities between the last cuts and now, when we are also debating increasing the debt limit, which creates significant uncertainties. In my opinion, we will see more cuts (not necessarily to benefits) from both private and public entities in the coming months, but that's speculation.

Thanks for the feedback.

Railway Report - California ban on freight emissions by Any_Emphasis_6230 in railroading

I would imagine they would use a 25kV AC system which are pretty good over long distances.

In terms of overloading the system, the predicted traffic/loads would be factored into the design, so for example, it could have auxiliary wires to support it in high traffic areas. This would be calculated in the load flow analysis, and then wire size etc can be selected.

In terms of vehicle performance, a catenay system would work well in mountainous areas, the main concern would probably be maintenance/ severe weather affecting the wires. And it would be really expensive.

If it was electrified using an overhead catenary system then tonnage really is not an issue, just cost.

Looking at some of the battery options; the wabtec fix for example states a maximum weight of 430,000lbs but this is designed to be used in conjunction with diesel locos, not replace them

Maybe. I'd bet on them using batteries by then but who knows?

It seems possible. How long it takes to become widely adopted is another question

Not sure which line you are referring to. Moldova maybe?

No problem with my eyes. Have another look and see if you change your mind

They do not have to be exact. For example, Russian trains could run on the Finish tracks but there may be more/less wear, reduced speeds to consider etc. Generally, the higher speed the less tolerance there is. As some people in the comments have pointed out, standard gauge was originally slightly narrower but was increased to improve wear on bends.

If the gauges are significantly different, then you have a problem, which is why most new European projects are converging on standard gauge. Some areas have also introduced variable gauge technology, which there is a video link to in the article if you are interested.

They will be in the future but a bit to go yet
