Referring to this. Maybe the systems are too drastically different to reconcile, hence the Galapagos Effect mention. After all, hasn't that been one of the main criticisms of Japan HSR export - more work to make it work with ETCS/whatever the Chinese use?

I believe Crossrail in the UK is also going to be similar to the classic Japanese railway - ETCS 2, (some form of) CBTC, and classic UK TPWS from west to east on a single line, with Crossrail trains sharing with regular suburban trains in the outer areas. If it works for them there, why not? (arguably Crossrail only has the Class 345 to worry about, whereas Japanese railways have a lot more)

Well, Crossrail has a helluva lot more money being spent on it than the Joban Line (isn't it the biggest European infrastructure project ever?)- any problems probably can be ironed out by throwing more money at it. JR East was looking more to having CBTC on the Joban Line as a benchmarking exercise (to compare with ATACS on the Saikyo Line) than anything else. Once they realized the costs were going beyond the scope of the project, they ended it, which was wise. I reckon with the success of ATACS on the Senseki Line, and it's (so far fault free?) recent activation on the Saikyo Line, JR-E figured ATACS was better long-term, while delivering more features than CBTC (such as grade crossing control and compatibility with multiple models of rolling stock on the same line) and "plug and play" with existing JR-E systems like ATOS.

Nikkei Asian Review

Is the demographic time bomb already making Japan less safe?

Spate of train delays blamed on lack of qualified engineers

FUMIHITO ISHIZUKA and YOSHIHIRO HARA, Nikkei staff writers

Short-circuiting shut down service on a busy Tokyo commuter train line for four and a half hours Wednesday morning.

TOKYO -- On a cloudy morning last week, every bus stop on the road leading to Tokyo's Shibuya district had at least 30 people waiting in line. A bus would come from time to time, but of course there was no room for a single passenger to get on.

The unusual sight was the consequence of the Den-en-toshi Line, a heavily traveled commuter line running directly under the road, stopping for four and a half hours Wednesday due to an electrical issue.

The rush hour stoppage drew a flurry of tweets by frustrated riders.

"Again? Enough of this!" one fumed.

"The line here is longer than you see at popular theme park attractions," another joked.

Though famed for punctuality, Japanese trains are seeing an increase in delays. In the past, delays were typically caused by accidents or severe weather. In recent months, however, electrical malfunctions have become a growing problem.

The Den-en-toshi Line, operated by Tokyu, also suffered a power outage on Oct. 19. In other rail trouble, damage to a substation caused delays Sept. 5 on East Japan Railway lines including the vital Yamanote Line, which loops through central Tokyo. A power outage halted service Sept. 12 on the Tokyo Monorail serving Haneda Airport.

Mind the skills gap

Though the responsibility in each case lies with the railway operators, some place indirect blame on a lack of qualified personnel working on the electrical infrastructure. Railway companies are popular employers, but the businesses that handle such tasks as building and inspecting electrical equipment have trouble attracting young people to take on what is seen as grueling work.

"Not enough talented people" go into such maintenance work, said Ryo Takagi, a professor in the electrical engineering department at Tokyo's Kogakuin University. "And students who join those companies show gaps in their knowledge."

New Tokyu 2020 Series



The 2020 series trains are being built by Japan Transport Engineering Company (J-TREC) as part of its "Sustina S24 Series" family.

The first 10-car trainset, 2121, was delivered from the J-TREC factory in Yokohama in late November 2017, and shown off to the media on 30 November 2017.

New style of overhead wires on the Toden Arakawa Line on a renovated section between Mukōhara and
Higashi-Ikebukuro-Yonchōme stations.








It's much different then the standard overhead wires.

Ueno Station (Ginza Line Ě Hibiya Line) remodelation



Tokyo Metro completed on December 13 the remodeling of the Ueno Station (Ginza and Hibiya Line).

Improvement works on seven Ginza Line stations between Asakusa and Kanda are almost complete just before the December 30th, day of the 90th anniversary.



Each with its style, the Ueno station on the Ginza line adopts an antique museum style while the station on the Hibiya line opts for a more modern design.



Thus, in the Ginza line station we find replicas of the lathes, classic posters, or even the first automatic panels that indicate that the train arrives.

Of course they have also had detail in the shopping areas, waiting areas or toilets.







"Echika Fit Ueno" is the name of the new commercial space with the typical that we can find in these underground galleries: bakeries, some accessories store, etc. "Mercury Patio" is a waiting area.























Now we take a look on the Hibiya line station:





New access n║4 with airtight door to prevent flooding.

Next, some amateur videos on the Ginza Line Station and Hibiya Line Station:






Merry Christmas to all!

Using QR Codes to operate platform barrier doors with different length trains? This is what is trying in Tokyo:

Quote:
QR codes to aid barrier door operation on train platforms



In a world-first, QR codes are being used in the operation of platform safety barriers at train stations — a development aimed at accelerating the installation of barriers and slashing the hefty cost.

The new system also has the advantage of being able to handle trains with different door placements.

Safety barriers to prevent people from falling onto the tracks are being installed on station platforms ahead of the 2020 Tokyo Olympics and Paralympics. The Tokyo metropolitan government launched a practical demonstration of the new system on the municipal Toei Subway lines last month.

When a train pulls into the Toei Asakusa Line’s Daimon Station in Minato Ward, doors open in a safety barrier that has been temporarily constructed on the platform. Affixed to each train door window is a QR code sticker measuring about 15 centimeters by 15 centimeters.



...

The metropolitan government worked with Denso Wave Inc., an Aichi Prefecture-based company that creates QR codes, to develop the world’s first method for operating safety barrier doors that uses QR codes. Trials of the new system began on Nov. 24.

...

Other types being tried

The central government and railway operators aim to install platform safety barrier doors at 882 stations across Japan by fiscal 2020, when the Tokyo Olympics will be held. As of the end of March this year, they had been installed at 686 stations. However, at the 260 stations used by 100,000 or more people daily, only 84 had barriers.

Holy hell, those Ginza line upgrades look amazing. Really surprising given how old they looked when I was last there in 2015. Very classy.

I wish Stockholm would upgrade some of its older stations too.
