Train 41126 ran via track 4 despite not immediately following anything and nothing behind

(Orange box around the train number on my mapping system indicates a 60kph route was given)

Train 13133 put on Track 2 at Korytow AI instead of 1 or 3 meaning the only option is to run it left track to Szeligi. Not really a show-stopper of a move, but it meant 4130 has to go round it on Track 1, and then meant 1335 got restrictive signals waiting for 4130 to clear from Track 1

Train 146047 closely following behind 1339 routed Track 1 to Track 4 at Olszamowice for no reason at all. I thought it was going to get 1439 past, but it didn't even bother doing that. (Which in itself would be a completely pointless move as we're all capable of doing 160!)

146047 again, side tracked at WP on Track 3 and then sent left-track to Knapowka on Track 2. Surely if it was going to send me left-track, from Track 1 surely would have been better, rather than from Track 3??

The left-tracking was a poor move as it then delayed/stopped northbound 3138 at Knapowka and crossed 146047 back from Track 2 to Track 1 again.

Service 16133 routed Track 1 to Track 5 to Track 1 at Idz, nothing ahead, nothing behind it apart from 1633 some 20kms back.

It looks like the AI received some fixes:

AI at SG held 40609 on Track 1 to run an early 244029 round it via Track 7.

The expected behaviour would be for the AI to let 40609 depart right time and hold 244029 outside or by running 244029 onto Track 5 or 7 but not committing the exit route for it -or- to run 244029 via Track 4 (which is what most human dispatchers do so it's not having to cross over all lines at the south of the station and then blocking the main line if SPl doesn't give the signal)

There was absolutely no benefit or anything to gain in the AI doing this move and letting it continue early as the 244xxx trains are booked to sit for well over 30 minutes at Sosnowiec Południowy anyway. All it did was delay 40609 for absolutely no reason at all.

Btw 244xxx should always run on track 4, because more often than not SPł won't be able to clear the signal right away and the train, standing at the home signal, will block all of SG.

[jeroezie]

It would be best, if theire was a way to get Spl to clear its entry signal, what the dispatcher at SG could see and afther that he clears the SG exit signal. But somehow that is difficult to explain to a player, let alone to program a bot to do this reliably.

[DazT]

Admittedly it's easier to do if SPl and SG is player controlled, but you need two decent players on both worth their salt. (ie. Know what they're doing)

SG player

• Offering the 244xxx on early and not waiting until it's rolling into SG (By offering it early SPl can plan ahead for it, rather than being caught off-guard - if they're worth their salt, they'd of been looking at the EDR and SRTD (and even TPV) and would already be planning for it 20-30 minutes beforehand!)
• Use a route that doesn't clog up the whole of SG should SPl not immediately be able to give the slot. so via 4 being the least disruptive. (As there is no booked traffic the other way on that Line 62 chord, there isn't a reason why they can't give the slot/line lock straight away when asked, however, I've had players in the past refuse to give the line lock because they've got "other traffic", what other traffic?! Give the slot doesn't stop them running to and from Line 660!)
• Sending 'Train departed' before the 244xxx gets around 500 metres from its last proceed signal (So the driver isn't on the brake as if it's gone Track 5/7 or 4 it'll be doing 40 anyway)

SPl player

• Giving the slot (line lock) early
• Dropping the barriers and giving the signal as soon as SG sends 'Train departed' and not waiting until the first track circuit shows occupied, if they're waiting for that it's already too late, the train has already passed SG's last signal on a restrictive aspect and approaching SPl's first signal at red.
• Recessing the 244xxx on Track 4 at Spl and not being clever and just launching it towards Dandowka unless there is an obvious workable gap to actually run it

How you'd ever get AI to simulate all that is beyond me, but there should be a better way than SPl waiting until the very last minute before clearing SPl1_W signal!

Then of course, there's the 244xxx itself, if player controlled you actually need a driver that knows how to drive and one that won't dawdle! (Know you routes, know your train!)

AI at Idz routed train 61102 (1) via Track 4 non-stop despite the only train following being early 6102 (2) which is booked to follow 61102 all the way to Strzałki anyway.



04:40, Noticed that the AI then sent 61102 from Track 4 to Track 1 (left track to Strzałki), so surely if it knew it was going to do this Track 2 to Track 1 south of Idz or Track 2 to Track 1 north of Idz would have been a better move, via Track 4 is just ludicrous!  (Personally I'd of just train it Track 2 all the way, but that's just me!)

4130 waiting for 42128 to clear (on 3), but then rather than waiting and running 4130 via Track 2 the AI decides to run it via Track 6. 

And then because the AI had made 4130 late (despite only being 1 late approaching Psary), it then decided to run early 3130 making 4130 even later.

SG AI holding 42930 despite being booked over the single line first towards SPl

In turn it also held 40609 (assumed for 24109, but see 0601hrs edit)

Both 42930 and 40609 are both booked before 24109 at SG R52

With regards to Line 660, if both trains are on-time (which I was at the time!), then the AI should be running the trains in booked timetable order over the single line. The AI had nothing to gain holding 42930 as 24109 is booked a ph at SPl anyway! More than enough time for 42940 to travel over the single line and arrive at SPl

0601 hrs edit: The AI after holding 40609 for 10+ minutes then decided to run it - ahead of 24109! So 40909 encountered delay for absolutely no reason at all, which in turn now delays 24109 and delaying (me!) even further on 42930. I went from being on-time to being 14 late over R52 Jcn.
