Rail signals don't work as intended. January 18, 2010, 12:02:12 pm I have problem with my rail signals. I think I have to use one more specific signal to complete my system. I want the trains to reserve always only one sections between two signals ahead. The problem is, the trains waiting on "choose" signal keep waiting for clearance until the whole way to destination is clear, what causes huge delays and losses. In the attachment (sorry for poor quality - forum size restriction) you can see this situation. In the centre there is a train waiting for clearance before station on "choose" signal. Its destination is mine coal on left edge. Almost all way is clear of trains, but the signal is still red, because of another train entering the coal mine station (half a wagon sticks out). The red arrow shows the current mechanism. When the train enters the coal mine station, the one in centre will reserve whole way to the station, blocking the way for other trains. I want it to move differently. Green lines show signals. I want the train to reserve sections from one green line to the next, no more. How can I achieve this? BTW: I use now two signal types, "normal" and "choose". "Choose" signals are only positioned at the entrances to stations.EDIT:Just had some thoughts. Before I started this game, I made several test infrastructures to know how the two signals work. I already had the two-way rail design on my mind, I just wanted to polish it. Probably this approach caused the problem. Now I've come up with three unsatisfactory solutions.1. Use only "choose" signals. It would look very stupid (I like aesthetics).2. Use only normal signals and change every line so it leads to different platform. It is huge amount of work now and later to ****ign existing and make sure no doubles happen in future.3. Create another parallel route and force the trains which do not stop at stations to follow it despite "choose" signal. However this probably wouldn't solve the problem, would require much work and cause higher expenses (rail maintain costs).I also forgot to mention that such situations occur everywhere in network.EDIT:First solution doesn't work.

Re: Rail signals don't work as intended. Reply #1 – January 18, 2010, 02:17:40 pm Sorry, your problem is unclear to me, please make a better picture. I think you might work with waypoints though, these are points on in the schedule of a line without a station. Quote Selected
Re: Rail signals don't work as intended. Reply #2 – January 18, 2010, 02:18:17 pm I've had similar Problems with Choose-Signals. They always try to reserve the entire way to the next stop on the schedule.You can set some free waypoints after the Station or inside it. I didnt try it out myself though. Quote Selected
Re: Rail signals don't work as intended. Reply #3 – January 18, 2010, 02:25:41 pm Choose signals are not recommended on tracks where through-trains operate. If you do this anyway, you should place a waypoint for the through trains shortly after the station that has the choose signal in front. Quote Selected
Re: Rail signals don't work as intended. Reply #4 – January 18, 2010, 02:27:26 pm What do you think about changing the signal itself, so it reserves the path to the end of the closest station?Does this waypoint require to be placed right after the station? I tried to set waypoint two tiles after station - it didn't work. Quote Selected

Make the through line shorter and trains will use it unless they need to call at a platform.Something like->-------------------->-- \_C____ppp___/ \_ppp_/ Quote Selected
Re: Rail signals don't work as intended. Reply #6 – January 20, 2010, 06:01:23 pm OK. I will write suggestion about changing the signal later. Now I know what to do to avoid such situations. Place the station perpendicularly to the line and place the signal off main line. /\| |S |>>S\/--PPPP>>C/\--PPPP| S| |\/ Quote Selected
Re: Rail signals don't work as intended. Reply #7 – January 31, 2010, 11:26:49 pm Hmm, I wouldn't do it like that, myself. The reasoning for having choose signals for platforms is normally to increase the number of trains which can call at once, which is normally because of high traffic density. A train slowing for a platform causes the train behind to stop and wait unless there is an alternative platform. However, since routes are normally bidirectionally equal in terms of traffic (circular routes being one exception), your setup implies a flat crossing for trains to move into the platforms, obstructing the other running line every time a train maneuvers into the station. Also, you still only actually have 2 platforms, which is no improvement over having one on each main running line (without any choose signals at all).If i had to do this I'd seperate the 'up' and 'down' lines like so: /\ | | S |PPPP--\/C---< >pre--\/--PPPPPPPP--/\-pre< >----C/\--PPPP | S | | \/ |avoiding any crossing movements and use a presignal (or long block signal) as shown so that the re-joining trains deferred to trains on the mainline - since it would make the stopping train check farther ahead before giving a green light than the stop signal on the mainline.
