Welcome to SimSig Feltham.

You will be controlling Feltham PSB, Wokingham S.B, Wimbledon Panel 5 (Barnes area) and (optionally) a simplified version of Reading station, all of which covers a total of 82 route miles. The simulation era covers the period for the above mentioned boxes up to how the area was in 2012.

Startup Options


Pre-sets the failure/delay probability and failure/delay duration sliders to levels relative to that difficulty. 'Gremlins' is a setting with excessively high failure rates, 'One of those days' is a setting with significant delays. Developer mode should be used when writing Timetables, this sets delay and failure probability to zero. Defaults to Beginner


Sets the prevalence of Temporary Speed Restrictions

Adverse Weather Conditions

Tick-box to denote whether Adverse Weather is currently happening. During adverse weather trains will be slower to accelerate and take longer to stop. Defaults to Off.

Level Crossing Controls

Selection box: 'Normal' is all crossings controls & penalties active, 'No Penalty' is just that, means you can be as evil as you like, so you don't get irate drivers waiting at crossings, 'No Crossings' is just that, all controls, penalties and calls have been disabled. Defaults to Normal.


In real life the signalboxes do not have TORR . This can be turned on with this option.

Reading PSB

Selecting this will enable part of Reading PSB to be shown.


Ash Vale Jn

The simulation fringes to Ash Vale Jn at Frimley - this is a simple entry/exit and no special process is required by the signaller as this is handled by the simulation for the single line section.


Fringes at Farnborough North / North Camp for Guildford via the 'North Downs' line.


North London Line

Multiple connections to the North London Line from this simulation, Two of these being pesent at Kew East Jn to New Kew Jn and Old Kew Jn. This is a straight forward area, but with the posibility of reversals from Old Kew Jn.


A simplfied area of control here, that enables the simulation to have the Waterloo <> Reading services captive. All trains that enter / exit the area via Reading will be using the 'Reading Depot Etc' slot.


Straight forward control handovers to Wimbledon ASC, first area being at Clapham Jn (Windsor Side) to/from Barnes, and the second being at Norbiton towards New Malden.


A straight forward section to Woking ASC at Addlestone Jn.


The area is mainly electrified 3rd-rail DC, with the following exceptions:

Kew East Jn area, Staines Down Goods Loop, Shell Mex Terminal, Up & Down Guildford lines & Reading New Jn area.

Control Area & Functionality



Regulation Strategies

Feltham is a two-track railway virtually throughout. It is therefore very important to ensure trains proceed in the correct order through the system, otherwise a fast train may get stuck behind a stopper with no opportunity to overtake. If trains are running late then use your best judgement - do you delay a late fast train even more, or delay an on-time stopper so the fast gets back into sequence?


Watch out for Down trains approaching Barnes that get overtaken by another Down train. It may be best not to set route from W523 or W525 for a stopping train until the train is nearly at Barnes.


Trains approaching from Strawberry Hill are generally timetabled along the third line to St. Margarets before joining the Up Main. This means that F18, F20, F16, F30, F32, and F36 can all be left in auto most of the time.


Wait for TRTS from the bay platform before setting route out of the bay. Otherwise a train may approach from Norbiton and be delayed.


Don't forget to set the route from F183. Because of the overlaps it is not immediately obvious if this route is not set: look at the signal post instead (white for route set; grey if not).


Make use of the goods loops for freight trains and empty passenger trains if they are out of sequence. There are no more opportunities to loop out-of-sequence down trains, or up trains via Kew.


Many services terminate at Ascot from the Ash Vale direction. If they do, ensure they're in platform 3 otherwise they'll block down trains until it is ready to depart.

Timetable Notes


Midnight, 04:00 and 14:00 starts are provided.

There are known platform clashes between the 3/8Sxx services and the regular booked services. With the frequency of the passenger services, there is no way of avoiding the clashes and were left as the timetable has them booked. (Mantis 38730)
