[QUOTE=Kalboz;32913507]What's this huge station outside DMK?/QUOTE]

You'd answer your own question if you took a quick look at the 2 maps above in the thread - see post #165.

It's the DM station for the SRT Dark Red line. future ARL extension (Eastern HSR line), future NE HSR line and SRT intercity services to the north and NE.
