Just spotted 8 trains in 15 seconds: 2 on monorail, 6 below. Earlier (late night in Japan) an inspection crew appeared to be on the center track, with ‘robotic’ carts following along on the track.
Our Charlotte replica streetcars are fed by overhead DC but converted by an on-board inverter to feed a chopper motor control, with a control handle that looks vaguely like a real streetcar – if you don’t know how a real DC streetcar works.
At the opposite end, are the old abandoned railroad stations, tracks and tunnel in the USA. There are some fascinating videos on youtube that railroad buffs may enjoy.
Here are an example :
Johnson Canyon Abandomed Railroad Tunnel – Arizona
Wonderful to see a great transportation implementation. Efficient and probably cost effective, my wish would be to have the camera closer to the tracks.
And since Japan remembers the past, it is not dependent on oil products from the Western Hemisphere that could be embargoed. That was the same reason South Africa was running coal fired stream trains decades after most of the world abandoned them, and replaced steam with electricity on the important routes.
The more I observe Japanese and Chinese culture, the more obvious it is how Europeans failed to acknowledge there are other cultures that were equally advanced while Europeans were obsessed with killing people who didn’t worship the right God.
If you want to locate this area, Italy Park is on the left side under the monorail and we are looking South. The main Tokyo train station is about a mile behind us. The most local trains are on the right side.
The camera appears to be on or near the Waseda Study Overseas (WSO) Centre.
First there was the train. (“Bahn” in German) … Then Germany invented “Auto trains” (Autobahn) which in the US are the “Eisenhower Interstate Highway system”
The concept doesn’t make sense to me and seems to be geared more toward getting money from taxpayers. I think it makes about as much sense as submarine train for underwater travel. (Paging Elon Musk!)
Data you can use – “A curve that allows a train to operate at the max speed of 220 mph would have a circumference of more than 50 miles, were it to make a complete circle. Going over mountains requires deep tunnels to level out the climb so that the grades are half as steep as those on interstate freeways.”
Actually, I can’t use that data. It has no source and was written by someone who slept through geometry class. The train is not running in a circle. The relevant measure used in engineering trains is turn radius. The allowed gradients (and freight trains) for Interstate highways is based on the horsepower needed to climb up the hill and brake going down hill. With few exceptions,freight is pulled by diesel locomotives which operate with an entirely different torque vs horespower profile, and the non-AC locomotives are seriously compromised by wheel slip.
There will be turns tighter than the maximum speed, which can be further mitigated by banking the track and/or leaning trainsets.
The one damning statistic is the speed requirement vs real world experience. Even so, the Japanese train operates with three different schedules. They have been building a maglev train that will be 86% in tunnels and go in excess of 350 MPH
So ultimately what is the point? The voters voted to borrow money to build something that is not possible. Is this story laying the foundation for Hyperloop? Indicting Donald Trump? Abandoning construction? Bringing in Chinese contractors to build the tunnel? There is a story in the past few days of one of those hurriedly built bridges collapsing into a river. Fortunately the bridge was full of no vehicles on the way to the empty ghost cities.
Yep, some journalist got that wrong. Minimum radius is 4.4 miles (28 mile circumference) for a 220 mph curve, and that is without ‘canting’ the track/rails.
Since I was a child, I always wondered “What is a shoefly?” Now, that’s to yesterday’s LA Time’s, I finally know. Unfortunately, my elementary school music teacher was about 60 back in the 60s and she is probably not reading this blog. 😉

My cousin in Boston had the same question. In order to rebuild the streetcar / Light Rail on the Longfellow Bridge, they used a shoefly to relocate the tracks during the 2 year long construction project. The historic preservation types wanted the riveting to be exactly as it was done when the bridge was built using an obsolete technique that nobody remembers how to do
The leftmost (East) pair of tracks are the Tokaido Shinkensen high speed rail, the most heavily used high speed line in the world

Okay, 5 trains in 90 seconds… it’s like watching a model railroad layout!

Lots of details about how ATC enables 3 minute spacing of Shinkansen trains into Tokyo Station.

Originally, trains had AC catenary with DC motors, but have switched to lighter AC motors. Here is a primer on why AC motors are a really big deal

Nikola Tesla would be proud… AC wins again.

In 1998, France loaned the original Statue of Liberty to Japan, and it was such a big hit that Tokyo put up their own replica in a tourist area

Seems to me that an “Autobahn” allowing cars to drive 150 mph would be a more cost-effective solution… especially if they were self – driving.
You can build a lot of nice highways for $100 Billion – https://www.nytimes.com/2018/07/30/us/california-high-speed-rail.html
