Capacity Increase on Subway Line 9

Subway Line 9, aka the "hell line" due to its congestion, will introduce 6-car trains from tomorrow.

Marred by low capacity and high demand, the line has struggled to increase capacity since its opening. The next year should finally improve the situation.

At the opening of the line in 2009, they were only 24 trains of 4 cars, which improved in 2011 with the addition of 12 trains. But then, with the expansion of the line to Gangnam area in 2015, demand increased drastically, and the number of trains remained unchanged (so the frequency decreased). Stress on the system grew, despite the addition of 4 new trains through 2016 and early 2017, bringing the total to 40 trains
(160 cars).

In 2018, introduction of new trains will finally be consequential, with the introduction of many cars.

From tomorrow, we will see 3 6-train cars introduced for express service, which is always welcome, but won't improve the situation much overall.

However, by June 2018, the plan is to increase to 17 6-train cars, and 28 4-train cars, for a total of 214 cars (45 trains), a 34% improvement compared to today.

Then, by December 2018, the line will be extended eastwards in the busy Songpa-gu area, and all 45 trains will have 6 cars (270 cars in total, although the line extension will bring down the frequency, so congestion should not improve significantly at that time). Apparently, by 2019, they will add 4 new trains to bring the total to 49 trains.

I still believe that despite the number of cars potentially growing from 160 to potentially 294 (+84%), the line will be quite crowded. In the end, I wouldn't be surprised if trains were further increased to 8 cars (at least for express service).

Also, this information comes from SMG, but labor unions are saying that the introduction of new trains, which require testing (juggling between cars of different size, and managing local and express service), may not realistically be done within the timeline announced by city hall to the public. So do expect potential delays in the introduction of these new trainsets.
