Peterborough - 1977 timetable, a second update - some questions.

Barry,

Thank you - but.

1) St. Neots US and Sandy US are not off-sim. They are not entry points so trains can't be started from there without having to arrive first. Similarly a train cannot be terminated there without repeated warnings that a forward working is needed, (as you would do with a passenger train in terminating station).

2) I put a test train of 200m length into Sandy US and it did not fit, standing foul of the USL. In fact, it was this that prompted the question. I reduced the length down to 50m and it still stood foul of the USL.

I accept Biggleswade DS is off-sim, as is Huntingdon DS 1 & 2, and St Neots DS.

Does anyone know the answer to the "Peterborough Spur" problem?

Vince

I'm also trying to create a movement to and from the Peterborough Spur, which is the short stub just to the right of the flyash line on the sim. My correspondent's memory is not perhaps as good as it was, but he recollects flyash cripple wagons being shunted into there,

I can set routes from 73 and 71 signal into the spur and the corresponding reverse routes from the spur GPS 68 to Crescent Spur and also to the Flyash line LOS 68.

However, I can't seem to find any route to and from the spur that will validate in a timetable.

Am I missing something?

1) have just tested this and St. Neots Up Siding's and Sandy Upsidings do allow entry to sim, I also set trains to arrive at St Neots up siding's and Sandy Up sidings but they do not leave the sim instead they arrive at the siding's and report in F2 Terminated, no more timetable trips

2) My test trains were 200m in length and they did not foul the points for me they went in to the siding's completely.

.

Added Info
Have attached my Test TT

Thank you

Further Info
I tested in one era (Original) and now testing in the other (Spalding Bi-Di) and trains arriving at St Neots Up Siding's seem to not arrive or terminate there they hit the buffer stops infact the train does not report in F2 that it has entered St Neots Up Siding's. Sandy results the same as original test Arrive at sandy Up Siding's and reports terminated, no more timetable trips, and has not fouled the points.

In attached TT you will find some valid route to and from the spur from the flyash.

but quick run down

trains entering from the spur the next location would be Peterborough Flyash Line (or Peterborough then platform set to FAL)

for trains going to the spur:
Peterborough Flyash line (or Peterborough then platform set to FAL) then next location would be Peterborough Spur (this is a exit point so no train activities such as next train or next location needed, any return working is a New train with entrance set to Peterborough Spur)

Important note

Even tho Peterborough Flyash Line and Peterborough (FAL) are in essance the same spot, to avoid TT errors if you have a join/detach/next train both location must match.

for example if you have a train which in the timetable says

4A00 has location
Peterborough Flyash Line J:0A00

And train 0A00 has
Peterborough (FAL) J:4A00

Will produce message on TT analysis of "Associated train **** is at different location"

Mark,

That's very helpful - thank you very much, I'll try and incorporate something into a timetable.

Okay, some answers at last. This is all from the current data.

Sandy Up Siding: 237m. It's also an entry point, but I'm not sure why. Perhaps that predates seeding.
Sandy Down Yard is more complicated. From signal 8 to signal 13 is 185m. Trains exit with the hand points reversed but enter between 8 and 13. Hmm, I'm not sure why it's done like that; that may be a bug.
St.Neots Up Siding: 420m. Again, also an entry point.
St.Neots Down Siding: exit point and, therefore, also an entry point.
Both Huntingdon sidings are exit points and, therefore, entry points.

Peterborough Spur is also an exit point (because it leads to sidings). So you need two separate timetables for the train and rules to link them. Valid previous and next (after entry) locations for the spur are Crescent Spur, Peterborough 799/800, Flyash Line, or Peterborough station with platform set to GL or FAL.

Mark: I can't see anything special about St.Neots Up Siding that would make it behave the way you describe. I haven't tried it myself yet.

You've got the Up Siding as a passing point!
