| | Ground
level Signal Box upgrade | |
| |
There is an ongoing project to install a fully
working lever controlled signalling system
for the ground level
track. |
| |
| Controlling the
Signals and Points. |
| |
A signal lever unit is being modified and
extensively altered to enable it to
be used on the ground level track
to control signals and points,
all operated from the signal
box. |
| |
It will operate with a combination of low voltage
(24 volt) electricity and pneumatic (air)
operated rams moving the
signals and points.
A compressed air ring main will feed the system
from an
air reservoir located in the signal box. |

lever unit modifications. |

This shows the unit at the end of October
2004.
Danny & David are busy fitting and wiring the micro
switches. |
| |
 |
| A closer view of the unit as of 31st October
2004. |
| |
 |
By the middle of November the main lever wiring
was well underway,
the unit has been partly dismantled for painting
(the levers are not attached). |

moved into the signal box. |

| The frame being positioned before fixing
down. |
| |
 |
| The frame is now in place. |
| |
 |
| The first lever has been positioned to check
alignment before the rest are fitted. |
| |
 |
| More progress on fitting the individual
levers. |

place. |

 |
| As of 9th January 2005 |
| |
 |
On the 9th January 2005, club members were given
a talk on how the system
will operate by Dave, one of the projects
designers. |
| |
 |
| Dave explaining the layout of a Signal Gantry,
which will span the tracks. |
| |
By July 2005 a lot of unseen work had been
completed, including
more wiring to the signal lever unit and the
first 'points' motor installed and connected. |
 |
Situated just outside the signal box, this is the
first points motor in place,
which has been installed to test the
various electrical and air systems. |
| |
By April 2006 a lot more work had been done
including an extensive
underground trunking system, to carry both
electrical cable and air supplies to the signal positions. |
 |
| |
|
| |
 |
| |
 |
| The wiring for the signal levers has also
progressed well. |
| |
Progress has been going well and by July 2006
more wiring and air lines have been installed,
also more connections
have been made to the signal levers. |
