About our Portcreek Junction Simulation.

This simulation has been developed specifically for beginners who have perhaps already got to grips with the basics and are now ready for the next step.  As well as the usuals of passing trains, the challenges of routing them and juggling conflicts through the junction are added, without the stresses of running a larger box represented by our Advanced series of Simulations

About The Prototype

The box which is the prototype for this Simulation was located on the former LBSCR and LSWR Portsmouth Joint Line.  It supervised the Junction between the Joint Line route between  Portsmouth and Cosham and the LBSCR line to Havant (where the LSWR route to Guildford and Waterloo diverged) and onwards to Brighton. Thus is can be seen that the ultimare destinations and routings of trains can be many and varied!

The box closed in 1968 after around a hundred years of faithful service - its functions being taken over by the then newly-opened Portsmouth Panel Signal box - which was itself superceded, after a traumatic start, by the Havant Signalling Centre in 2007


This stretch of railway has always been busy, with a steady stream of trains heading into and out of Portsmouth to a range of destinations around the South and West of England, with traffic for Salisbury, Southampton and the West taking the divergent route at Portcreek Junction, whilst trains for London Waterloo, London Victoria and Brighton etc continue along the Mainline to diverge at Havant. Of course, as elesewhere on the South Coast, summer Saturdays with the added holiday traffic - including non-stop Waterloo - Portsmouth services, and countless special trains for all over the country - were something special. Indeed, with over 25 trains per hour at the peak, it is quite likely that Portcreek was one of the busiest double junctions on the whole of the Southern Region. Needless to say, we have included just such a timetable with the simulation...

Traffic and Operations

The main line at Portcreek was electrified on the Southern Railway's 660V DC Third Rail system in 1937 and  much of the traffic therefore consists of multiple unit passenger trains. The line to Fareham and Eastleigh and the West however, remained the province of loco haulage until after Portcreek Junction box closed.  Correct routing and describing of trains without causing delay or causing mayhem at Fratton or Portsmouth is therefore key to success!
The timetables for the simulation are set in the mid 1950's and early 60's and therefore the loco-hauled trains are mainly in the hands of steam locomotives - often of rather ancient vintage.  It would be unwise to bring a 6-coach local to a stand at the Home
Signal on the sharply curved Down Branch if it is hauled by a T9 4-4-0 which might struggle to get its train underway promptly. Luckily, in the simulation, we do not replicate the torrent of abuse from the crew which might have resulted in the real world of the 1950's!!
