Trent was always probably my (edit: second*) favorite sim back in the day - just due to the sheer scale of it and the wide variety of movements and routing possibilities. Unfortunately it seems to have been left in the dust, even as far older sims get brought into the new world. Any plans for an updated loader sim version of Trent? Even as payware I'd happily shell out for it. * 1st Favorite being the semi-official NLL scrolly that floating around at one point. That really deserves an update as well.

I agree. I love Trent and Sheffield as well. Really hoping for an updated version of these two great layouts. The mix of freight and passenger movements always offers a superb experience.

I suspect the answer to that is yes, but one day. Aside what you are asking I'd much prefer to see a 1980s era sim done of Trent as the vareity of traffic flows would be significantly greater than a modern era tt. For me personally a 1980s era of Trent would be at the top of my list of things to see done. However this is in the hands of Kurt & its anyone guess as to wjetjer it will be done & when. Maybe we should start a betting syndicate to wee what gets done first & when. That aside Trent is probably my favorite sim despite me living about 2 miles from Clay Cross Junc. But Toton was probably my favourite place to go watching trains when I was train spotting back in the 1980s & early 1990s.

I've always loved the Sheffield 1983 TT, but once you've played some of the newer scrolly sims, going back to Sheffield is like passing through a time warp.

I could not agree more these two sims are simply superb to play and always interesting I go back to them quite often as I worked through the area when a passenger guard at Peterborough Regards Cabooseman

They have not been forgotten, I can assure you. The main issue with both Trent and Sheffield is they did some clever things that required the use of custom code which devs could use freely back then and not a small amount of it either. Custom code ceased being supported for SimSig developers some time ago and everything is now done in data instead so those features that used custom code would have to be implemented using different techniques that are now available which means basically means some parts of the sim would have to be re-written from the ground up. That's not an insignificant task. There's also how much time Kurt has to throw at updating them as well. Log in to reply |

Out of interest - which clever things are these? And how do you do things nowadays that are unique to one area - or is the core code flexible enough that you can do even this using just data?

" said:Out of interest - which clever things are these?

However I can give you an example of something from one of my sims. The NSKT between Llanrwst and Blaenau Ffestiniog in North Wales Coast needs "custom" phone calls. Back before a recent core code update this would have needed to be written in "custom code" however it can now be written in the data, in such a way that when I use it in another sim, it's fairly easy to modify to suit.

" said:Out of interest - which clever things are these? And how do you do things nowadays that are unique to one area - or is the core code flexible enough that you can do even this using just data?The data that the core code interprets doesn't just include static descriptions of the layout, such as track circuit lengths and signal locations on the diagram. It also includes a restricted and specialized programming language that lets you do things at particular times or in response to particular events. For example, two lines of the data for Fenchurch Street are: These describe two of the entry points. ULC= says what subroutes to lock (and so light up in white) when a train is entering. BER= says which berth to put the train's identity into. But note that Up East Ham EMUD also has a CMD= entry. This says "execute the following code whenever a train enters here". In this case, the code is simply "trts,S900", which fairly obviously means "trigger the TRTS at signal 900". As another example, here's part of the logic for the SPAD alarm at Euston: Things beginning with L are internal variables that take a value from 0 to 63. Things beginning with C are freestanding bits of code triggered in various ways. In this case, L1SPAD etc. are internal variables that are set to indicate a SPAD at that signal. So L2ARM is set (to 1) when S2 is red, track circuit 54 (the platform track circuit) is occupied, track circuit 55 is clear, and the route locking from neither the A end nor the B end of T55 to the C end is active. From memory, 55 is points facing to the platform, so this means that it arms if a train is standing at signal 2 when it's red and nothing is approaching the platform. L2ARM is cleared (to 0) if signal 2 clears, track circuit 54 is clear, or a route is set inwards over track circuit 55. L2SPAD is then set if both T54 and T55 are occupied with the alarm armed, and cleared by an explicit clear action. Thus L2SPAD is set if a train straddles signal 2 at danger after having been only on the platform and with no inbound route set. LSPADALARM is a simple union of the 18 possible individual signal SPAD alarms. LSPADACK corresponds to a button on the screen. A left click when LSPADACK equals 1 will set it to 2; a right click when it equals 4 will set it to 0. State 0 is shown as a hollow button, state 1 as a flashing red one, states 2 and 3 as a solid white one, and 4 as a flashing white one. Thus clicks on the button acknowledge the alarm. LSPADCLR is set when the alarm is active and LSPADACK has reached state 2 or above. It clears when the alarm cancels itself. So if the button has been pressed to acknowledge the alarm, L2SPAD and friends will attempt to cancel themselves. If the SPAD condition has actually cleared, they will succeed and so LSPADALARM and then LSPADCLR will return to 0. If the condition is still there, L2SPAD and LSPADALARM will immediately set again. CSPADCHECK is executed once a second. The code says: if the alarm has gone off and LSPADACK is not in states 1 or 2, then put it in state 1 and execute the CSPADALARM code as well. If the alarm isn't active and we're in state 2, move to state 3. If the alarm isn't active and we're in state 3, move to state 4 and execute the CSPADCANCEL code as well. The CSPADALARM and CSPADCANCEL bits of code each have an associated timer (indicated by TYP=D). Executing CSPADALARM outputs the message "Train running away", sets the timer to go off in 10 seconds, but only ticking when LSPADACK is in state 1. When the timer expires, CSPADALARM will be executed again. So this gives a message at regular intervals. I hope this is enough to give you an idea of what flexibility we have.

Thank you very much for the detailed explanation - it does indeed make it a lot clearer now. It took me a few times going over it, but I believe I understand everything you said now. It seems then that pretty much anything unusual to a sim area that is required could be done with this language - it seems very comprehensive (albeit quite an unusual language, though I'm sure it's easier when you're used to it!), which is pretty cool.

Back ontopic, after playing it a bit more, I can see why Trent has a lot of custom code - there does appear to be quite a bit of "non-standard" stuff in there (probably because some of it wasn't at the time part of the core code).

If I remember an explanation by Kurt correctly, even CCTV level crossing weren't part of the core code until development of Trent was already way under way, which is why only Bulwell Forest crossing will give a message (and play a sound) when the 'Clear' button becomes active.

The same also applies with things like setting TSRs and historical era selection, Just goes to show how much effort has been expended on the core code over the years.

Would you prefer a new thread ? I think posting where it was last mentioned makes sense. Even if the reply is 'not at the moment' At least this can lay dormant now until the time is right and we are all surprised. Blessed are the true believers, for only they shall walk the Path, and they shall be welcomed unto the realm of the Ori and made as one with Them.

Rule 10 probably applies: 10) Bumping: Don’t post to an old topic simply for the purpose of keeping it alive. But if you have something useful to add then it is preferable to add to an existing topic (no matter how old) than to start the same or similar topic again. Though how it applies is probably open to interpretation. Peter I identify as half man half biscuit - crumbs! Log in to reply The following user said thank you: mfloyd |

To expand a little further. The Trent developer has very little to do with SimSig anymore and hasn't done for a number of years. Without the original data, or input from him there is little any of us can do.
