Hmmm, yes I see what you mean. Actually at first, it was never planned to make a second tramline. The reason is that the middle tracks only get a small part of the platform, which could only fit a single X-10 trainset.
Though, considering that the rest of the tram tracks haven't been layed, it is no problem to change it to a Pendeltåg line.
I guess we will be getting a P5 then
Oh, and another minor update. Kalmsholma C has been changed to Kalmsholma Södra. The reason being that I think it was way too small to be a central station, and it didn't have much space to park passenger cars on. I'm still trying to build a a good candidate for the Centalstation.
