Double Track Cross (2X2)
Have you ever had the problem of crossing tracks going parallel to each other. And there was not enough space (width) to build a proper cross which doesn’t slow down trains.
This construction makes it possible to cross 4 tracks (2X2), for example a typical mainline (LL__RR) near a station area or to split some tracks going at wrong points. Of course this works also with only two tracks (1X1), but its not worth to show it.
The keypoints:
+ very small (area is 6×19)
+ double bridges/tunnels don’t cause trains to jam
– it may cause problems with small trains (TL: 2/3, because bridges are quite long)
– its not in the stable releases, you need one of the newer OpenTTD nightlies
I’ll also add it to the Junctionary,
enjoy it and happy building
Diagonal bridges could make it smaller and cheaper…
Of course,
but we don’t have diagonal bridges 🙁
one more tile can be shaved off if southern tunnel exits go SW and then merge next to bridges rather than under… so i guess 6x18x3?
I fail to see the need for those huge bridges. A version with smaller bridges doesn’t need double bridges and hence can be smaller. Find it at http://openttdcoop.ppcis.org/wiki/index.php/Image:Junction2.png
The right one is a version with single bridges (7×11), the left one with double bridges (9×20). Both are slightly wider, but not nearly as wide as a full cross. And no problems with small trains 😉
With some minor actions (placing the bridges right next to eachother; buildonslopes is needed), it is possible to shrink them to (6×10) and (7×16), respectively
