Confusing routes, confusing displays

On Saturday 18 March 2023, two new lines were added to Tokyo's railway network: Sotetsu and Tokyu Shin-Yokohama lines. Sotetsu Shin-Yokohama line was extended from Hazawa yokohama-kokudai (hereinafter referred to as Hazawa YK) to Shin-Yokohama, while Tokyu Shin-Yokohama line was opened from Shin-Yokohama to Hiyoshi. There are now hundreds of through-services every day from Sotetsu to Tokyo via Tokyu lines and vice versa.

As the biggest railway project in more than a decade has been completed at last, it is expected that Shin-Yokohama, an interchange station of Tokaido Shinkansen high-speed rail, will be even more convenient and easier to access for people not just in Kanagawa Prefecture but also western part of Greater Tokyo.

However, when I visited the new stations on the very first day, I found that the new through-services are confusing and even chaotic as described below.

This is a route map on a wall. It covers all stations managed by SEVEN railway companies that the new through-services would call at: namely Sotetsu lines as well as JR Saikyo line, Tokyu Meguro and Toyoko lines, Tokyo Metro Fukutoshin and Namboku lines, Toei Mita line, Saitama Railway Saitama Stadium line and Tobu Tojo line. It is extremely hard to find one's destination without help.

Destination displays show confusing information as well. In Japan, trains that call at every station are generally written as "Local" with white (or black) letters. But this display is so colourful that it is not easy to comprehend what do they mean. Displays on trains also adopt the same colour patterns. Apparently not a good idea for those with colour vision deficiency.

The colourful displays indicate routes of each train, as (hopefully) the map above shows. Since trains for Tokyu Toyoko line and others for JR Saikyo line run towards the same direction, it is vital to make it clear which line does the train go. For example, there are trains for Ikebukuro via Tokyu Toyoko and Tokyo Metro Fukutoshin lines and others via JR Saikyo line. The most confusing ones can be observed in the weekend morning: a train departing Hazawa YK at 7:51 is for Kawagoe via Saikyo line, while another one at 7:55 is for Kawagoeshi via Toyoko, Fukutoshin and Tobu Tojo lines. Both trains call at Ikebukuro despite they run completely different lines. Not a few passengers will certainly take a wrong train and thus pay 140 yen more than what was supposed to be.

Any timetable revision always causes a certain level of misunderstanding and confusion, but the Sotetsu-Tokyu through-services are hard for everyone. Generally speaking, a new railway is something to be welcomed, but these new ones are quite tricky.

Ueno Zoo Monorail: the demise of the first monorail in Japan

Ueno Zoo Monorail is a 0.2 mile-long monorail operated by the Tokyo Metropolitan Bureau of Transportation, connecting west and east areas of the Zoo. This is the first monorail in Japan, which was opened in 1957. The line lies almost entirely within the Zoo, but the line was constructed in accordance with former Regional Railway Act 1919. Even today, the line is operated and maintained on the basis of Railway Business Act 1986, which means that this Monorail is registered as a genuine railway despite it looks a kind of amusement ride.

Ueno Zoo Monorail was built as a test line of "alternative means of transportation" which must be more efficient and punctual than trams. It is based on German Wuppertal Suspension Railway system with some modifications. However, it became clear that monorail is not always suitable for the city of Tokyo, as it is expensive to build while it is capable to have only limited number of passengers. The Bureau decided not to make any new monorail, and instead started expanding underground and bus networks.

In January 2019, the Bureau announced to suspend the operation of the Monorail from 1st November, as the current rolling stock got old. Its future is bleak as it costs 1.8 billion yen (approx. 17 million USD) to introduce a new fleet. The Bureau intends to have discussions with specialists, visitors and local residents, but the Monorail is likely to be closed permanently.

Currently, one unit of 40 series (built in 2001) runs every 7 minutes during opening hours of the Zoo. It costs 150 yen for an adult and 80 yen for a child, but note that admission fee is required to get into the Zoo. It takes about 90 seconds from east to west areas and vice versa. The last service is scheduled to be held on 31st October.
