I decided to implement a new subway intercity connection between Arcens and Marlande. The link was created in Marlande and appeared at the city boundary in Arcens:



Close to the boundary is a road with a tram-in-road (TIR), changing to a subway tunnel to pass under railway tracks. A GLR+bus combo (black circle) will be replaced by a GLR+subway combo moved to the right, with a roadside bus stop nearby.


The next picture is rotated to the left (north is on the right) to better show the part of the avenue on which the GLR+bus combo station is located, where the Sims board buses to Marlande. (The station has lost its GLR shelter - some silly prop issue that I am too lazy to fix). The ramp to the highway is immediately next to the station. The stats on the station show that it is quite overused, although still within tolerable limits:




The planned changes, extending to a longer stretch of the avenue, are shown in the next picture:



1 - new GLR-on-avenue to subway transition
2 - current GLR+bus combo station to be replaced by a subway+bus combo
3 - current GLR+subway+bus combo station to be replaced by a subway+bus combo
4 - new GLR-on-avenue to subway transition


The planned work was executed. This is the new subway view of the area (properly oriented):



1-4 as above; 5 is the new GLR+subway combo on the road close to the city boundary; 6 is the new subway tunnel linking to Marlande. At this time it terminates at the GLR+bus combo station near the highway ramp; it
may be extended further into Arcens later.


Here is the view of the avenue (rotated) with the changes implemented:




After running the city for a few game months there is already a decent traffic on the new subway link:




The next step will be to run Marlande to 'acquire' that traffic on the subway link.

Brian, in answer to your question about the zoning, here is a zone view of Arcens:



1 - the residential area close to the boundary with Marlande, where Sims go mostly to work in Marlande
2 - residential areas that are closer to the nearby commercial area
3 - commercial area
(That part of Arcens is pretty self-contained, there is barely any traffic with zones on the other side of the large body of water).
