Possibly one for the Developer, who will know for certain why it happens.
Drivers reject any route into the bay if their train is too long, defined as bay length minus 2 metres. This is intended to simulate route knowledge.

I wonder, can "Waiting for correct route to be set" also mean "SimSig detected an attempt to shunt a train of Class 1, 2 or 3 and this is not permitted"?
Not in general, no. That is, there's nothing like that in the core code.

However, the developer of a sim can implement specific tests for any specific route. So they could check the headcode and reject the route, in which case you'll get the message.

(It's also possible for the tests to be dynamic, so that, for example, the driver will reject the route if given a yellow signal but will accept it when given a green, or will accept/reject based on the position of some unrelated points, or .... Not that any developer would do such a thing ... (cough Kurt cough).)

I had wondered why it seemed necessary to assign a special description to any train that has to reverse at Harrow siding while it is in the siding, e.g., J201-7 terminates at Harrow & Wealdstone (emptying its passengers), becoming K201-8 to enter the siding as ECS since Class 5 descriptions aren't used for LU ECS, then changes to K201-9 once it's out of the siding. Now I understand - SimSig must only let in the empty versions of these trains by their TDs
No, SimSig is not examining the TDs.

These changes happen because that's what the real Working Timetable does. The sources I have list these trains with a 7 character TD instead of the usual 4 characters. So these are 2J01201, 5K01201, and 2K01201 respectively. The real displays show J201 or K201, so that's what I used. The LU WTTs would talk about "train 201 run 5", with the runs changing when the train reverses direction.

Eurostar trains still run as class 9.

Eurostars use 9I** (nine-india-*-*) and 9O** (nine-oscar-*-*) descriptions in the UK, which become 91** (nine-one-*-*) and 90** (nine-zero-*-*) descriptions in Europe.

9OXX are the Paris Trains
9IXX are the Brussels Trains

Where do they get their 7, 8 and 9 suffixes in SimSig? Is that also in the real WTT?

No. As the manual said, I added the suffices myself, ignoring the letter. Think of them as "part run" numbers (if I had access to the actual run numbers I could do better).

Okay, all is clear now. Thanks Peter for the timetable link.

Just replayed Wembley Sub and am revisiting this thread.

This sim offers a choice of Willesden bay lengths (67 or 87m), but what is the reason behind this, as LU trains won't fit in anyway, and this bay can only be used for ECS trains? Having just played the sim, I can't recall a single instance of being disadvantaged by the shorter bay. Is this for future TTs which are set in the years before the bay was lengthened? Maybe Clive can supply the answer.

I'm slightly confused here - it's a while since I've played this sim, but where does the idea that the bay can only be used for ECS trains come from?

I had been under the impression that entry into the bay was only via shunt signals to allow traffic to and from the TMD arrival road, but yes, signal 23 at Kensal Green is a main signal and some late night trains do depart from platform 2 for Camden. But I still fail to see where a shorter bay might have any bearing on the default timetable.

There used to be 3 Car Class 313 EMUs work the Euston - Watford "DC" line services, which were approximately 60 metres long. When the newer Class 378s were introduced, a fair portion were delivered as 4 car units (80 metres approx), so they would not fit into the Willesden Bay as a 4 car. Now, all of the 378s are 4 car (due to be lengthened to 5 over the next couple of years), so it would make sense to lengthen the platform.

It acts as a sort of era mode, you wont find any disadvantage with the 2009 TT as the 313s were still in operation.

The bay was increased in length, and making it an option was a good test for a new feature in the core code, so I made it an option. From memory (I'm not near my codebase) trains will reject the route into the bay if they're too long.

It has no other effect (though you'll notice that the starting signal changes position on the screen depending on the bay length).

I have a vague idea that bay was longer back in the day too - not only that, there were two bay roads as shown here http://www.signalbox.org/diagrams.php?id=393

No sign of a spline or french curve - all hand drawn! Wonderful sketch.
