Hello, Hopefully Noel will see this thread. I'm very impressed with Huddersfield, as you can probably tell by my username, it's one i've been waiting for, for a long time. I just wondered on the following things: 1) How does the "SimSig logic" work for Ace's Sidings? for example if I shunted a TPE 185 into there during out of course working, will the sim remember it's there (even when it disappears off the sim). Is it possible to fill the sidings up and have units trapped on the mainline? 2) For trains coming from Stalybridge towards Huddersfield, if I had to hold a unit outside the station for a prolonged period of time (I.E. no platforms available for ten mins or so) Would it be better practise to hold the train outside of Gledholt tunnel rather than holding the train at the signal inside Huddersfield tunnels? Many thanks Log in to reply |

" said:As mentioned in the manual, the sidings have finite capacity (approx 510m). When you start the simulation, the total length is 'unknown' (i.e. you could put 510m in or take 510m out), as you take trains out and put them in the amount of length 'occupied', 'empty' and 'unknown' changes accordingly. Warnings will be displayed as the sidings reach capacity or run out of stock.

Hi, In answer to thy questions, 1) Yes, Aces will fill up and stop you putting trains in there once full, similarly once it's empty nothing will enter from there until you put something in. 2) Not too sure without inquiring of the signaller. Glad you're enjoying the sim, it's nice to know I've pleased someone out there. Noisynoel Last edited: 08/08/2015 at 21:53 by Noisynoel Log in to reply The following user said thank you: 2W34 |

" said:" said:This (apart from the warnings) is core code logic, so applies to any sim that enables the feature.As mentioned in the manual, the sidings have finite capacity (approx 510m). When you start the simulation, the total length is 'unknown' (i.e. you could put 510m in or take 510m out), as you take trains out and put them in the amount of length 'occupied', 'empty' and 'unknown' changes accordingly. Warnings will be displayed as the sidings reach capacity or run out of stock. A location is given a capacity and a range of current occupancy. For example, suppose a location has a capacity of 200m. At sim start, the range will be set to [0, 200], meaning that the sim knows that at least 0m is in use and at most 200m is in use. Suppose you want to send in a train of 50m. The code will see that there *could* be 50m free because the occupancy might be 150m or less. So it allows the train in. Now the occupancy is at least 50m, so the range is set to [50, 200]. Now a train of 80m wants to enter from the location. The code will see that there could be a train that long in there, so it allows the train out, making the occupancy [0, 120]. Similarly, a second train of 80m entering will change the occupancy to [0, 40]. But suppose a third 80m train wants to enter. It's now not possible to have a train that long in there, so the request is refused. Next a 100m train wants to go in. There must be room for it no matter what, so the occupancy changes to [100, 140]. It's followed by a 70m train. This will fit if there was no more than 130m in there, so the range will change to [170, 200]. Finally, let's have a 125m train enter. That's possible no matter how much is currently there, so the range changes to [45, 75]. I hope that makes things clearer. A couple of notes. Firstly, the code only looks at train lengths. It has no idea about types, electrification, or anything else like that. So it will happily let the place fill up with 153s and then send out a Pendolino. Secondly, each route into or out of a location can have a different maximum train length assigned to it. This is applied in addition to the above mechanism; it's intended to simulate things like headshunt sizes. So I can have a depot with a main entrance that has no limit and a back entrance that only allows up to 50m long trains because everything coming that way has to reverse in a (hidden from the sim) headshunt. But both routes are taken account of in the 200m capacity (i.e. you can have 5 40m trains come in the back way and then go out as a single 200m train via the main route).

Slightly off topic, but am I right to think that Euston and Huddersfield are the only sims to use this feature so far?

No, I have implemented it on Horsham as well in Carriage Sidings 2/3. I don't believe any other Dev's other than myself & Clive have used the feature as yet.
