It was a plan to do this , but the cost to compensate the neighbor who should be tore down is too high and it is too hard to negotiation with the China Railway Company for building new tracks above part of the CR's depot. So Shanghai government gave up undertaking the plan.

To upgrade the capacity of these two lines in alternative way , SH metro is purchasing more trains , expanding the depot of line 3 . Trains will run more frequently at northern part of line 3 .

Shanghai Metro Line 16 unveils first 6 car train

3+3 linked train to start operating. I guess they finally acquired enough rolling stock to do this.

It's uncommon for metro trains to have x+x configuration. Normally new cars are inserted in the middle to increase the capacity. Is it going to be a permanent configuration for all trains on Line 16? Will the trains eventually become 6-car instead of 3+3?

I mean, they were originally running Line 16 trains only every 10 minutes at rush hour with 3-car trains. No wonder, these trains were become super-crowded.

Is there really a global rolling stock shortage or is the issue only because of laws that require it all to be made domestically?

There are linked metro trains. Guangzhou uses 3+3 on their B1 series rolling stock for Line 3. So does the new DT5 trains on the Hamburg U-Bahn. Also the Berlin U-Bahn HK and IK stock run in a 4+4 consist.

I believe it is a protectionist issue where China is opening subways faster than they can build trains to service them. However, Shanghai Metro has been very slow to order trains compared to the other Tier 1 cities. Beijing and Shenzhen have been so far especially diligent at placing supplementary and optional orders for rolling stock to augment existing lines.

Is there any reason for this rather than inserting middle cars? It's definitely more expensive in this way because the cab cars are more expensive to build, and the platforms may need to be a little longer. Capacity may also be less.

Apparently Shanghai is working on a trolleybus eBRT line under the Yan'an Elevated Road. The design capacity is planned to be 15,000 ppl/hour/direction. This looks like it will be a local/distributor line with an average station spacing below 900m.
