However there is a bottleneck where traffic jam occurs easily. See picture below.
Yeah, I know.

The thing is that the last time I actually played this scenario I was planning to extend the "incoming goods" station area - which is basically the main reason for keeping trains waiting long times. As you can tell, a majority of the trains waiting at the so called "waiting area" south of the station area are "incoming goods" trains, and with a more sufficient system the station would work better. I also believe I had in my plans to create another line to somewhat minimize the bottlenecks when train arrives/leaves the station.
It should be noted that there are some problems with other station areas as well, but I need to take a closer look at the map in order to understand what I was thinking when building the system up...
However, since I played this map new patch features have been implemented and I'm looking forward myself to continue this map.

hope you won't mind me being too greedy
Sure, if only I knew what tunnels and stations you're talking about!
UPDATE///
Oh silly me...I assume you refer to the image I posted myself above!

Actually, the station in question is made by Andres as a replacement to the in-game station, (made before we could actually use additional ones). It can be found

The tunnel is worse. I can't remember exactly where I found it. Anyone else perhaps?
