Acknowledgements

Original sim written by Karl Latham.

To my team of testers, and timetable writers, thank you for the effort you have put in over the last year to get this sim to where it is today.

Finally to Geoff Mayo, and the others too numerous to name that have brought SimSig this far - Thank You!

Overview

The Leamington Spa and Fenny Compton simulation contains the line between Warwick (exclusive) and Banbury (exclusive) including the branch lines to Coventry and Kineton MOD, with two eras from 2003 and 2006.

The 2003 era depicts the line in the last full year of operation of Fenny Compton mechanical signal box, and the original NX-panel in Leamington PSB.

The 2006 era depicts the line in the original Westcad workstation, before the resignalling of the fringes to Coventry and Hatton, with transfer of those areas passing to the West Midlands Signalling Centre at Saltley.

Within the simulation are two different workstations:

  • Leamington
  • Fenny Compton (2003 era only)

Features

The simulation covers approximately twenty-one miles of the Great Western Railway route from Didcot to Chester (DCL), with four miles of the branch line to Coventry, and the three and a half mile branch line from Fenny Compton to the Ministry of Defence site at Kineton. In the 2003 era, this distance is slightly less as Fenny Compton Signal Box fringed with Banbury North Signal Box at Cropredy, where an emergency ground frame was provided, released from Banbury North.

The main line is double track throughout, with middle roads at Leamington Spa Station, and goods loops in both directions at Fenny Compton, the down being bi-directional. The northern fringe is to Saltley Power Signal Box and the southern fringe to Banbury North Signal Box. In 2006 era, this line is Track Circuit Block throughout. In 2003 era it is TCB between Warwick and Fenny Compton, and then Absolute Block the rest of the way to Banbury.

The Coventry Branch is double track from Leamington Spa for the first three quarters of a mile until Milverton Junction, where it becomes single as far as the fringe with Coventry Power Signal Box at Kenilworth South Junction. In both eras, it is Track Circuit Block, with slots provided in either direction.

The Kineton Branch commences in the sidings at Fenny Compton and is single track throughout. It is worked by No Signalman Key Token, with a single token normally left at Fenny Compton. In 2003 this would have been in the Signal Box, in 2006 it is in a locked instrument situated adjacent to the stop boards at the Kineton end of the sidings. In reality the 2003-era staff would have been handed over to the Driver by the Signalman at Fenny Compton, however in SimSig, the modern system is replicated in both eras for simplicity.

Scenarios and Options

Scenarios

Perfect: No delays and no failures - perfect for the new player.

Beginner: Normal running, no lines or platforms closed. No trackside failures but limited delays and disturbances.

Standard: Normal running, no lines or platforms closed. Limited temporary speed restrictions, trackside failures, delays, and disturbances.

Hard: Normal running, no lines or platforms closed. Temporary speed restrictions, trackside failures, delays, and disturbances.

There are scenarios to shut either the Through roads at Leamington Spa Station, or the Up Goods Loop at Fenny Compton.

Options

Train Operated Route Release (TORR) can be switched off in the 2003 era, this is only applicable to Fenny Compton Workstation.

Work Station Specifics

Leamington

Leamington Spa Station is a four-platform station, two of which are North facing bays. In between the two through platforms are middle roads which are used for passing freight trains and occasional regulation. The through platforms are signalled for permissive working, which is only authorised for contingencies which require the permission of Operations Control.

From Down Bay Platform 1 you can depart towards either Hatton or Coventry, but you cannot arrive into this platform in the Up direction, trains using it have to shunt. This bay platform is authorised for full permissive working.

From Up Bay Platform 4 you can only depart towards Hatton, but can arrive from either Hatton or Coventry. This bay platform is authorised for full permissive working.

The Field Sidings are in reality out of use, but are included in the simulation as they are still present within the interlockings, and at the dates of the simulated eras all of the infrastructure was also still present.

To grant the slot to Coventry PSB for trains in the up direction, you will need to set a route from the greyed out signal LN56 to signal LN54. This will lock points 236 at Milverton Junction normal.

2003 Era:

This is the original area of control of Leamington Power Signal Box dating from 1985 when it was commissioned as the first conventional application of Solid State Interlocking.

You will control from the fringes with Saltley Power Signal Box (at Warwick) and Coventry Power Signal Box (at Kenilworth), to the fringe with Fenny Compton Signal Box just south of the former Fosse Road Emergency Ground Frame. All three fringes are worked by Track Circuit Block.

2006 Era:

This is the layout as installed by the Cherwell Valley Resignalling Project in May 2004, which saw the closure of Fenny Compton Signal Box, the shortening of control area of Banbury North Signal Box from Cropredy back to the outskirts of Banbury itself, and the replacement of the original panel in Leamington Power Signal Box for a WestCad workstation controlling three Solid State Interlockings (since replaced with the first WestLock to be installed in the United Kingdom).

The fringes to all other signal boxes are worked by Track Circuit Block.

For details of operation of the Kineton Branch Line, see the Fenny Compton section below.

Fenny Compton

Fenny Compton Signal Box is replicated here as it was just prior to closure in May 2004. It works Track Circuit Block to Leamington Power Signal Box, Absolute Block to Banbury North Signal Box and Token to Kineton.

There are up and down goods loops, the down loop being bi-directional in the 2006 era.

There are three sidings off the Down Goods Loop. In 2003 these were all through sidings, in 2006 Siding 3 had become a dead-end due to the Kineton end of it slipping down the bank. The branch line to Kineton MOD starts at the end of these sidings.

Trains bound for Kineton should be routed into any through siding at Fenny Compton, Once the train is at a stand, you should release the staff by clicking on the "Release Staff" roundel. Once the indication shows "Staff Out", you can authorise the Driver to pass the stop board (2006 era) or clear FC9 (2003 era). Note that the ability to authorise past the stop board (which is the driver phoning in as at any normal red signal) or the ability to clear FC9 are NOT interlocked with the staff (as in reality), so if you attempt to do either without the staff being released, the train will proceed to Kineton without it. Once the train arrives at Kineton, the Person in Charge will phone up to advise you that the train has arrived complete, and the NSKT system will indicate "Staff at Kineton".

For trains from Kineton:

  • If the staff is already at Kineton, the PIC from Kineton MOD will phone up and ask for permission for the train to enter. You can either tell him to call back, or grant permission. If you grant permission, the train will enter and proceed to Fenny Compton. When the train arrives at Stop Board OL5156 (2006) or FCSTOP (2003), you will have to talk the train past it into the sidings, and once the train arrives he will automatically surrender the staff.
  • If the staff is at Fenny Compton, the PIC from Kineton MOD will phone up approximately twenty minutes before the train is due to depart requesting the staff. You can either tell him to call back shortly, or tell him that you have released the staff. If you tell him you have released the staff, the staff will automatically be released to the PIC, who will then take it to Kineton by road. Once he arrives, the staff will show "Staff at Kineton" and the train will proceed as above. If the staff is already out at the time of the request, you will only be able to tell the PIC to call back shortly.

In 2006, Points X are Normal for the route from Siding 2 to Kineton and Reverse for the route from Siding 1 to Kineton.

In 2003, Points X are Normal for the route from Siding 3 to Kineton and Reverse for the routes from Sidings 1 and 2 to Kineton. Points Y and Z are Normal for the route for Siding 2 and Reverse for the route for Siding 1.

The "F" roundel is white when the points can be moved, and red when they cannot be moved.

To clear the Down Home signal FC46, you either need all the track circuits clear upto and including the overlap for FC103, or the berth track circuit to FC46 occupied. This is the prototypical control that existed to enforce "board-to-board" signalling.

In the 2006 era, there is double red protection for Fenny Compton in the down direction. If OL3165 is at red, OL3163 will approach release from red, so beware if you replace the signals to danger with a train approaching. Any train past OL3157 will receive a change of aspect.

Level Crossings

There are five user worked crossings in this simulation, all between Fenny Compton and Banbury as follows:

Crossing Name Era Protecting Signal Up Protecting Signal Down Notes
Wormleighton 2003 FC74 BN48 To protect from Banbury North, leave block at NORMAL
2006 OL3164 OL3161
Clattercote 2006 OL3160 OL3159 No Telephones
Whites 2006 OL3152 OL3151
Jefferies 2006 OL3152 OL3151
Little Bourton 2006 OL3152 OL3151

Multiplayer and Chaining

The simulation will chain to the Saltley and Coventry simulations in both eras. It will eventually chain to Marylebone IECC in the 2006 era as the layout at Banbury is different in 2003, but not replicated in the Marylebone simulation. This is awaiting an update to the Marylebone simulation.
