Fenchurch Street was the first SimSig simulation ever developed. The software framework was still being created and development went down some blind alleys. The source of the simulation has been lost, but a few copies of the executable survived.
I have spent some time reverse-engineering this executable to recreate the data for the simulation. And so we have SimSig Fenchurch Street Reborn!
As discussed below, this simulation recreates the original as far as possible. In particular, the data is as it was in the original with no changes. However, the data and core code have been brought up to the latest standards and features (e.g. the provision of sticky notes).

My thanks to Geoff for the original simulation and allowing me to do this, to Ben Woodward for the 2009 timetable, and to all my testers for their hard work.
SimSig Fenchurch Street basically covers the area of one of the workstations at Upminster SCC. It covers the LTSR, or "Thameside" line, from Fenchurch Street to Upminster and Ripple Lane yard, plus connections to Bow Junction and Woodgrange Park (these are the only remaining links between this line and the rest of the "classic" network, though Ripple Lane also connects to HS1).
The Up direction is leftwards and the Down direction rightwards.
In the default mode, the diagram consists of two parts, one above the other.
Upper section: This consists of the line from Fenchurch Street to East Ham EMUD, with the single track branch at Gas Factory Junction towards Bow Junction. As can be seen, there are four tracks for a short distance out of Fenchurch Street, allowing trains to be reordered on arrival or departure. The platforms at Fenchurch Street at permissive , and controls exist to prevent a second train being called-on if there isn't enough space left in the platform for it. There is also a goods loop at Gas Factory Junction.
Lower Section: This is based around Barking station. This is where the LTSR route splits - both branches head for Southend and Shoeburyness, but one runs directly via Upminster, while the other diverts along the north bank of the Thames to Tilbury before turning north to meet the first at Pitsea. The latter branch sees a lot of goods traffic from the various docks. The Upminster branch is bidirectional from just west of Barking all the way to Shoeburyness, though this is only simulated as far as Dagenham East.
There is also a connection to the other lines around London via Woodgrange Park, and this is also one terminus of the London Overground "GOBLIN" service.
The basic speed limits are 20 mph at Fenchurch Street, then 40 mph to Limehouse, a short break back to 20 again, then 50 mph to Gas Factory Junction, 60 mph to East Ham, 45 mph through Barking, and 70 mph from Barking to Upminster.
The standard 25kV overhead equipment powers all lines in the simulation except platform 1 at Barking.
All the scenarios and options have been added in this version; there were no such in the original simulation.
The four scenarios and the four levels of problem are all self-evident. "Normal"/"None" corresponds to what players of the original simulation would have experienced. ARS was provided in the original simulation and has not been changed.
The tick boxes in the options have the following effects. If all the boxes are left unticked you will have as close as possible to the original simulation, warts and all.
Any of the fringe locations can be told that the line is blocked by putting a special code into the relevant train describer berth:
There are two timetables supplied with the simulation. Firstly, the "morning" timetable is that provided with the original simulation, with some minor bug fixes, and represents a weekday morning service (plus, for no known reason, one evening goods service - that being 6E04 entering from Up Ripple Lane Dep at 20:41) at the time the original was written. Secondly, Ben Woodward has provided a 2009 timetable.
The following description is of the "morning" timetable. There are a total of 218 schedules in the timetable involving 130 trains entering the simulation and one divide. The entry points are:
East Ham EMUD 10
Woodgrange Park 32
Ripple Lane 4
Dagenham Dock 29
Standard railway descriptions (headcodes) are used in SimSig, as always. The first digit is the class of train. The second character is a letter, which usually denotes the route taken by the train. The remaining two digits simply give each train its own identity.
The train classes are:
The route letters found in the timetable are as follows. They are only a guide; always check the actual destination of the train.
The "c2c" service runs between Fenchurch Street and Shoeburyness via either Upminster or Dagenham Dock. In the peaks there are fast services that omit some of the stations. Empty stock works in and out of the depot at East Ham. One or two services per day run to or from Liverpool Street instead, using the Woodgrange Park route. The trains are all class 357 "Electrostar" 4-car EMUs, usually coupled into 8- or 12-car formation.
The London Overground 'GOBLIN' (Gospel Oak to Barking line) service runs between Gospel Oak and Barking; these normally using platform 1 at the latter, although they can also use platform 7 aswell. It is operated by DMUs - previously Class 150/1s, but nowadays Class 172/0s.
There are normally a lot of freight services between Ripple Lane and the Woodgrange Park route, but the rest of the line sees little or no freight.
This section lists the internal codes (which in many cases are TIPLOC codes) for the timetable locations in the simulation, and also provides a brief description of the less-obvious locations. These codes are used when using the timetable converter.
When a train enters the simulation a different code - an entry point code - is used. These codes are shown in italics following a » symbol. In general, the entry location should not be the first location in the train's timetable as well.
EHAMUP (signal 900), EHAMDN (signal 1019)
EUPMAIN (signal 214)
EUPRIPL (signal 804) In practice, these two can be used interchangeable for down trains
EUPTILB (signal 628)
The following problems are known about in this release.

This section will be updated as bugs are reported.
The following are part of the original simulation data. Even where they are not prototypical, they have been retained in the interests of reproducing the original simulation as much as possible. They are not bugs and will not be fixed.
These are Adobe Acrobat PDF files. If you don't have Adobe Acrobat Reader installed on your computer you can get a free download of the latest version from the Adobe website .
*Fringe Box, signals not controlled in this simulation.
Non-prefixed signals are controlled by Upminster (UR).
