History & Construction
Making a start
Construction of the Acton Miniature railway started in 2004. The original track layout was very simple with a loop at 'Depot Approach' and a single line up to the current location of the point into the loco servicing siding.

Opening and the first year
The railway opened to the public on Saturday 26th February 2005 during the Museum's 'London Transport in Miniature' open weekend.
Sam Mullins, Director of London's Transport Museum, cut the ribbon and shortly after, the Little Red Train operated the first passenger service.
Despite the sub-zero temperatures and a brief snow shower on the Sunday, the AMR's first weekend was very successful with a three train service in operation and 879 tickets sold over the course of the weekend.

The June weekend saw the first temporary signals installed on the railway, to ensure that operation was as safe as possible. After the October open weekend, the railway had carried over 1,900 passengers.

Winter 2005/6 work
The winter of 2005/6 saw much work taking place to extend the railway. This included:
A new siding was added off the Depot Approach loop, parallel to the departure track. This provided much needed storage capacity for spare stock or for static display.

A locomotive servicing siding was added between Harrison's Crossing and the end of the line. This provided further stock storage space and a place to service steam locomotives away from the passengers.

The line was also extended further towards what is now Wesley's Halt.
New Stock
In late 2005, the railway was donated a loco and two wagons, giving the railway its first resident stock. The loco could not have been more suitable, being a model of Metropolitan Railway 'Metrovick' electric loco No. 12 'Sarah Siddons'.
The prototype is preserved and has been used to run special trains on the London Underground network.
The loco and wagons were all built to 7½in gauge, rather than the AMR's 7¼in, but have since been regauged, with Sarah Siddons making her debut on passenger services in March 2008.

2006
March 4/5 saw the first open weekend of the year, along with the first steam hauled trains on the Acton Miniature Railway.
The railway operated an intensive three train service and proved very popular, carrying over 1000 passengers during the weekend despite the cold weather.
On static display were Sarah Siddons, and a part-completed Metropolitan Railway 'A Class' loco.

After the May open weekend, work began on the extension to Wesley's Halt.
Tracklaying occurred in August and the loop was brought into use for the October open weekend, albeit without being used for passing trains.
The new loop came into its own in March 2007 when, in combination with new signalling, it enabled the operation of a very efficient 3-train service.

The Future
The railway is now in a period of consolidation, however the eventual aim is to extend to Ealing End, which will be sited next to the gates visible in the background of the photos above.
There are also plenty of other jobs to be going on with, including the installation of permanent signalling and a permanent signal cabin, along with general maintenance on the existing line.

Get Involved
The AMR and the London Transport Museum Friends are always in need of volunteers. For more information about joining the Friends, please see the LT Museum Website.
If you are particularly interested in helping out on the AMR, please get in touch to find out more. No miniature railway experience necessary, just enthusiasm and willingness to learn.
The Route

On departure, the train runs through the loop track (pausing to wait for an arriving train to clear the single track section if necessary)

The train then heads onto the single line up to Wesley's Halt, passing over the level crossing to the picnic area at Harrison's Crossing.

The train then reverses and re-traces the route, often waiting for a minute or two for a passing train at Wesley's Halt and arriving in the straight track at Depot Approach, where passengers alight.
Finally, the train shunts empty back to the departure track at Depot Approach to collect the next trainload of passengers.
In the future, the line will be extended to Ealing End, next to the Museum Depot yard and the gate to Ealing Common Depot.
Signalling
Signalling is important for safe operation on any railway with more than one train in use, and the AMR is no exception.
At present, the railway has a set of temporary colour-light signals for the Depot Approach & Wesley's Halt areas, which are operated in accordance with London Underground practice.
Provided by Adrian Allum, the signals are made out of repeaters recovered from a full-size signalbox, with hoods made out of card. The signals are controlled by a single operator using a switch panel at the Down end of Depot Approach loop.
There is also a shunt signal which authorises trains in the arrivals platform at Depot Approach to shunt forward to the departure platform. This is made out of a signalbox track circuit repeater and is controlled by the station master using a foot-switch.

To ensure only one train at a time can be on the single track section between Depot Approach and Wesley's Halt, a token system is used.
There is only one token, and the driver of a train must possess it before being allowed to enter the single line from either Depot Approach, Wesley's Halt or the locomotive servicing siding.

The signalman hands the driver the token authorising him to proceed on the single line to Wesley's Halt.
At present, all of the loop points are spring-operated, with points to sidings 'clipped-and-padlocked' into the correct position as necessary.

The long term intention is for the railway to be fully signalled, with continuous train detection. The whole railway will be operated from a signal cabin near Harrison's Crossing.
