なぜ地下鉄・南郷７丁目駅だけホームが３つあるのか？実はこんな理由が…「ＨＢＣもんすけ調査隊」2021年7月23日放送

A request from 6-year-old Kobayashi Kanato, who lives in Sapporo. (Requester) "Why does Nango 7-Chome Station have three platforms? Please tell me!" Why does Nango 7-Chome Station have three platforms? What does it mean to have three platforms, anyway? First, I headed straight to Nango 7-Chome Station... At first glance, it looks like there are two platforms, but upon closer inspection, I see there's another platform on the right! Most Sapporo Municipal Subway platforms are either "island" platforms, with tracks on both sides, or "side platforms," ​​with tracks in the middle. However, Nango 7-Chome Station has tracks on both sides, as well as one in the middle. In other words, it has three platforms. What? You think this is also a platform? What observation skills you've come to expect! However, when I actually got there, I discovered there were no platform doors, so I couldn't get on the train. That's why there are three platforms. Passengers "Hmm, I wonder? I'd never really thought about it. I guess it's like this because there are so many people..." "I've heard that this is where they put in new trains and stuff." "Is it because it's an old station? I wonder if they did something here in the days when turnarounds weren't possible." After staking out the platform for a while, I noticed trains coming in on both tracks, but not a single train on the middle track... What on earth is going on? To find out the truth, I contacted the Sapporo Municipal Transportation Bureau. Sapporo Municipal Transportation Bureau, Takahashi Hidehiro, Operations Section Chief "You'll understand if you go to Nango 7-Chome Station in the morning." What on earth is on the platform in the early morning? As soon as the shutters at Nango 7-Chome Station opened, I rushed onto the platform...and what did I find there? A train was parked on the middle track, a track that shouldn't be in use! Hidehiro Takahashi, Operations Manager, Sapporo Municipal Transportation Bureau "We now use this platform every day to depart the first train at 6:00 AM. The side platforms need to be used after closing time for maintenance and other purposes. For this reason, we park trains on the middle platform the night before." All stations from which the first train departs on the Sapporo Municipal Subway are at the very end of the line, except for Nango 7-Chome. Why did they go to the trouble of building a third platform at Nango 7-Chome Station to allow the first train to depart from there? Hidehiro Takahashi, Operations Manager, Sapporo Municipal Transportation Bureau "The Tozai Subway Line originally ended at Shiroishi Station. In 1982, the line was extended to Shin-Sapporo Station. At that time, due to the high number of passengers using Shiroishi Station as the starting point, we scheduled the first train to depart from Nango 7-Chome Station." The Sapporo subway was established exactly 50 years ago, in 1971. As a public transportation service unaffected by snow and cold, it began operating between Kita 24-jo Station and Makomanai Station on the Namboku Line. Two months later, the Sapporo Olympics were held, and Sapporo's cityscape began to expand. To coincide with this, in 1976, the Tozai Line opened between Kotoni and Shiroishi. It was later extended to Shin-Sapporo. However, a new problem arose at this time. Takahashi Hidehiro, Operations Manager, Sapporo City Transportation Bureau "It takes about 19 minutes to get from Shin-Sapporo Station to Odori Station. Because it's so long, we decided to have another first train depart from Nango 7-chome Station, which is located between the stations." With the extension of the Tozai Line to Shin-Sapporo Station, the departure time of the first train from Shiroishi Station, which had previously been the starting point, would be delayed by 11 minutes. So, to accommodate passengers who were not yet on the extension, the first train from Nango 7-chome Station was created. This is the travel time from the first station to Odori Station. You can see how far Shin-Sapporo is. So, to support early morning travel in Shiroishi Ward, the first train from Nango 7-chome Station was created. First Train Passengers "I think this is great. It's a lifesaver for me since I'm working." "I'm working until now, and normally I'd take the train from Nango 18-chome, but when I get to Nango 7-chome, the first train is there, so I take it. I can get home about 10 minutes earlier." "I have to get to work early. They tell me, 'The first train is at 6, right?' I don't know if that's a good thing or a bad thing." #Question #Search #Hokkaido #Sapporo #hokkaido #sapporo The HBC Monsuke Investigation Team is dedicated to answering questions submitted via social media!
