2009TT---Freight timed to stop right in middle of the complex junction?

Leeds City was certainly entertaining enough once you rememeber what goes where on the Leeds West JN---But one thing confused me and make life full of pain is that apparantly almost all freight I encountered in first 10 hour here are timed to STOP at places such as Whitehall JN or Engine Shed JN. Was it a slight mistake in TT that they should pass instead of stop then resume, or they indeed need to stop here blocking the track to Bradford and Huddersfield?
As the file shows 4E55 and 4S78 are timed to stop at Whitehall JN for a whooping 30+min. They indeed leave immediately once signal was clear but I still wonder why it was set as stop in TT?

Standing on the curve is Whitehall Jn (north, for 4S78) and Engine Shed Jn (south, for 4E55), and both do fit OK.

There's three things going on here.

Firstly both trains in the save are considerably early. If you let early trains run you are going to have some fun, and ARS routes by timetable. So in the save both trains are giving priority to some ECS.

Secondly with the times in the timetable set as standard stops you will sometimes get freight trains waiting for time. Using the 'pathing stop' type would be more appropriate especially for the stops not on the curve, as that ensures trains will move off when signalled.
eg 4E55 at Whitehall West, 4S78 at Engine Shed Jn.

If the long stops were for crew changes, then actual crew change activities or equivalent rules are needed in the TT.
Unfortunately there is no rule for different locations, so you cannot have '4E55 must not depart Engine Shed jn until 20 minutes after 4S78 arrives at Whitehall Jn'
That would need a 'station' called Whitehall curve which I suspect is not in the WTT source

No not a mistake that is what happens and used to happen at Whitehall and Engine Shed Jn with the Anglo Scottish coal moves and Gyspum trains to and from Kirkby Thore and any other freight traffic, the trains souldn't foul the junctions at each end whitehall curve can esily accomodate a 66+21 HTA/HHA/HYA/HXA's

Hunslet yard is owned/operated by freightliner. If DB and GBRF used it, they'd have to pay a fee to do so, as opposed to sitting at Whitehall which is free.

Also you'd need ground staff present at Hunslet which costs money compared to sitting on the mainline waiting time.

Will things be better back in BR's time as yard could be shared, or the GF's operator means it still cost too much?

While I could not find a 2009 'YH' WTT in the NR archive, there is the 2007 version with similar trains.

This shows the Engine Shed Jn / Whitehall Jn times as pathing/regulating stops, there are no crew changes. Seems likely crew usually did Carlisle - Power Station - Carlisle in one shift.
This will still result in the ARS in SimSig have 'early' trains give priority to other nearby conflicting trains, in a fairly simplistic manner. ARS is rule based, and does not do well when there are more than two trains to consider.

Having 'hard' stops is a timetable bug, but in fairness this timetable may predate the newer stop types such as 'regulating' needed here. Freight trains can leave early some of the time anyway.
