DONCASTER "LX"
SERIES
This cache is part of the 31-cache series "Doncaster LX" (LX is
standard railway terminology for "Level Crossing").
The great majority of the caches in this series are drive-by,
and most are not particularly challenging - although there are one
or two that may make you scratch your head a little ;-)
The caches are a variety made up of the following:
- Tupperware
- 35mm
- Nano
- Camo Tube
- and one or two others.........
With the odd exception, we aren't going to tell you which caches
are which - you can find that out for yourselves for the most part!
In addition, there won't be clues for a lot of the caches, but you
won't struggle to find them too much.
The final cache in the series is a BONUS cache, and the
co-ordinates for that cache are contained in one way or another in
fifteen of the caches in the series. Sometimes you will have to
answer a question to get part of the co-ordinate, at other times
the question and/or the answer will be in the cache container. It
will never be loose in the container, however - it will always be
taped to the inside of the container or be attached to the logsheet
when present.
The questions that you have to answer will be based around the
level crossings themselves - you might, for instance, be asked how
many flashing red road lights there are at a particular crossing.
And that is the whole point of this series - we would like to
impart a little extra knowledge about level crossings, and if you
come away from it knowing a little bit more than you did, that is a
good thing. Clues to the questions will always be found within the
text or at the crossing itself - you will never have to go away and
do research on the internet, for instance.
SAFETY INFORMATION
All of the caches are placed within about 300m of the associated
level crossings, but none are located in a position that will cause
any safety implications. Of the very few that are located closer
than the recommended 150 ft (46 m) of the railway, the railway is
completely fenced off from the cache location, and retrieval will
cause no safety issues. At only one cache (LX8) is the user
expected to cross the railway on foot to get to the cache location.
This traversal, however, can be accomodated easily by following the
signs at the level crossing (Booths No. 1). If any cacher feels
uncomfortable with using the crossing in the normal manner, please
contact us. It is not necessary to visit this cache to complete the
series.
Finally, we would ask that the following basic rules are adhered
to when completing this series:
- Never park at emergency parking sites at automatic
crossings
- Be aware of, and considerate to, local
residents
- If an alternative parking Waypoint is provided in the
cache listing, please use it
- Always observe any signs and/or notices detailing how
the crossing is to be used
We hope that you have fun with this series - we certainly had fun
setting it!

MCB-CCTV
Because CCTV cameras are used by the signaller to determine that
the crossing is clear of obstructions, they have to be available at
all times, and also be useable in all conditions. You should be
able to see the cameras at the crossing on a tall post - there are
two identical cameras. Only one is in use at any time, but the
signaller can switch between them.
The CCTV image is transmitted either via copper co-axial cable
or, more recently, fibre. There are often diverse routing systems
so that the image can still be transmitted in the event of cable
problems. If the CCTV system does fail, there are two options. The
first is that an operator is despatched to site to act as the
"eyes" of the signaller. He talks to the signaller on the
telephone, and confirms when the crossing is clear. In the event
that the remote transmission system fails, the local operator can
take complete control of the crossing and raise/lower the barriers
under instruction from the signaller.
To ensure that the image is viewable at night, the crossing is
also provided with plenty of illumination. In addition, the cameras
have a DAY/NIGHT setting which is selectable by the signaller.
Cameras of the vintage of this crossing are black and white (as are
most security cameras), but the advent of fibre-based transmission
systems in recent years means that colour systems are the norm for
new installations.
As far as possible, the cameras point as near to north as
possible - this ensures that there is minimum interference from
sunlight - especially reflections from wet roads caused by
low-lying sun position in winter.
