Train usage

Epping - Ongar Railway

The Epping-Ongar railway runs from Epping Forest via North Weald to Ongar. It used to be part of the Central line, but was closed to passenger traffic in 1994. The line has since been re-opened as a heritage railway, running under diesel and steam power. The connection at Epping to the Central line still exists, and so in the simulator, you may enter Epping Station. While the line was still part of the Central Line, trains to Ongar mostly ran as a shuttle service from Epping, using track 1 at Epping, while trains towards London used track 2 (the track next to the station building).

In reality, trains from North Weald towards Ongar end at "Epping Forest". This is only a reversing point; there is no platform for passengers to get on/off the train. The EOR does hope they can, in the future, build a platform along the track a little closer to the Epping Underground station (where passengers can interchange to/from the Central Line).

As a result of a poll among users on the forum, the Epping-Ongar Railway in the simulator has been equiped with 3rd/4th rails, to enable London Underground trains to drive to Ongar once again. This is however only done on the service tracks, not on the sidings.

The levers in the signalboxes at North Weald and Ongar have been animated and are coupled to the switches and signals. However, as the switches and signals in the simulator are operated via the CVL system, they can not be operated manually. Only one switch at Ongar is manually operated by using the corresponding lever in the signalbox.

Destination codes:
E - Epping
F - Epping Forest (coming from Ongar / North Weald)
N - North Weald
O - Ongar
Z - Shunt from track GN or HN (at North Weald) to LN, accespoint for the Sidings.

Central Line

The Central line has been created from Epping to Woodford.
As it is practically directly next to the main route, a small section of the Hainault branchline including Roding Valley station has also been added. You'll find this line branching off roughly halfway in between Woodford and Buckhurst Hill.

Destination codes:
E - Epping
D - Debden
L - Loughton
W - Woodford
H - Roding Valley

Other locations

Loughton Sidings

At Loughton, there are 10 sidings available, each suitable for one train. These sidings can be reached from all three Loughton platforms.

Woodford Sidings

At Woodford, there are 6 sidings available, each suitable for one train. These sidings can be reached from reversingtrack W21.

Signalling system

Central Line

The Central line in the simulator can be used with these train protection systems:

  • Coded Manual
  • Restricted Manual
  • Tripcock
  • ATO (for use in combination with the simulators AI function)

Coded Manual

Coded manual works almost the same as ATB on the Simvliet/Rijndam networks in the simulator (however it does use codes ATB does not have, so ATB-only trains are not compatible). It sends coded signals via the running tracks to the trains, where they are translated into maximum allowed speeds which are then enforced by the on board systems on the trains.

Restricted Manual

Like Coded Manual, but doesn't need tracksignals as it will only allow a slow (ment for shunting only) speed.


No protection from overspeeding, but emergency braking when passing a signal at danger (including signals showing the white signal aspect).
In reality, Tripcock is not installed on the Central Line.


Uses Coded Manual signals, and drives the train itself. In the simulator, use this in combination with the AI function; the ATO start-buttons will be illuminated when the train is in motion, and the traction handle will be disabled.

The light signals

The lightsignals use red, green and white signals (and occasional yellow). When driving manually, the red and white signals may not be passed (red signals may only be passed when a shunt signal shows a diagonal red line at the same location). Trains driving on ATO may pass white signals.
On approach to a red signal in the simulator, you will get a 25 km/h speed limit from the Coded Manual ATP system. Therefore, when getting a 25 km/h speed limit, watch out for red signals.

Epping-Ongar Railway

The Epping-Ongar Railway has its own signalling system. Light signals are used, and also semaphore signals at North Weald and Ongar

The light signals

Lightsignals can be green, yellow or red (double-yellow indicates the next signal will be yellow), and can have a route indicator.
This route indicator can have different forms; at Ongar a destination track number is shown when entering the station.

And at North Weald (coming from Epping), a letter can be shown; "L" (for "Loop track") for track 1, and "B" (for "Bay track") for track 3.
Signal NW2.jpg
If the signal is red, but also shown two small white lights in a diagonal line relative to each other, then you may pass as a shunting movement. It means a path has been set, but the destination track is already occupied.

Train Protection

ATB tracksignals are present at the Epping-Ongar Railway, to make it possible for the other trains in the simulator to run here. However, as the maximum speed for the EOR is 25mph / 40km/h, this is the maximum speed that is enforced on the line (also when driving under Coded Manual). If you want to drive faster... Set your train to Tripcock or disable the ATP.
