The following notes will be of use to writers of timetables for the Portsmouth simulation.
The simulation is based on the signalling in use prior to 2006. As a result of the resignalling work undertaken at that time, a significant number of changes were made to the timetables after that date. The major change was the altering of line names between Fratton and Portsmouth & Southsea, which are summarised in the table below.
|Line name in sim||New Line Name||Line Code Used|
|Up Main||Up Main Line||UML|
|Down Main||Up and Down Line||Not used|
|Down Relief||Down Main||Not used|
|Back Road||Back Road||BKR|
Platform 1 = 8 Car
Platform 3,4 & 5 = 12 Car
Platform 3 = 10 Car
Platform 4 = 10 Car
The following table gives details of where platform numbers are mandatory, along with any platforms which are acceptable alternatives.
|Location||Platform Numbers in use||Suitable Alternatives|
|Portsmouth & Southsea||1, 2, 3, 4||None Permitted|
|Portsmouth Harbour||1, 3, 4, 5||Platforms 4 and 5 are suitable alternatives for each other|
At all other locations the use of platform numbers is not required.
The attention of the signaller is drawn to the platform numbers at Portsmouth & Southsea High Level. These two platforms are numbered the 'wrong' way round, and it is to be noted that although platform 1 can be used as an arrival platform for Down trains, the signalling will not permit the running of Down trains towards Portsmouth Harbour. It is also recommended that any terminating services use the low level bay platforms, even those operating under the VSTP arrangements.
Fratton Depot complex has 3 entry locations as follows:-
Entry location = Fratton Old Yard
Exit location = Fratton Old Yard, Fratton Depot Fuelling Point, Fratton Storage Sidings
Entry locations = Fratton Carriage Holding Sidings, Fratton CSD,
Exit locations = Fratton C.H.S, Fratton CSD
Entry locations = Fratton Recp
Exit locations = Fratton Recp
Also at Fratton is a location for Fratton Staff Halt, which is on the way into the C.S.D. This means that trains stop part way into the depot.
