one road, one direction, not double direction. ¿Are there any pak ????
I may be wrong but you used to just click twice to change from one side or the other. It may have changed though.
If you want to use both lanes for the same direction, you can't. I recall some threads from the old forum where this was discussed also. Basically, the answer was (and I ****ume it still is) that the simutrans engine/core hasn't been developed making this possible, so it would be too hard and too severe to change simutrans enough to make that possible. Correct me if I'm wrong, though.
As far as I know (I didn't try this) it should be possible it the latest nightlies. Just make your road fit for one-way traffic only, in the usual way. Thanks to Isidoro, vehicles will overtake each other if possible, thereby using the second lane.
;)! very well, thank you all for your answers
