XBR Electronics Ltd - News Update
Hey! Your copy of SeaMonkey is
more than four weeks old. Unless you are using the latest
release or nightly build, bug reports get rapidly less
useful the older your copy is.
So if you're not running the latest
release (SeaMonkey 2.0.13), we could use your
help testing either that or the latest
nightly build. (Be warned that nightly builds are
development software, and there is no guarantee that they
won't fry your processor, insult your mother, or cause you
to break out in a nasty rash.)
Hey! Your copy of SeaMonkey is
outdated and we offer a newer testing version. Unless you
are using the latest (testing) release or nightly build, bug
reports get rapidly less useful the older your copy is.
So if you're not running the latest
release (SeaMonkey 2.0.13) or the latest
testing version (SeaMonkey 2.1 Beta 3), we could
use your help testing either those or the latest
nightly build. (Be warned that nightly builds are
development software, and there is no guarantee that they
won't fry your processor, insult your mother, or cause you

Mk2
WSP For C313 (01/07/11)
A Certificate of design Conformance has been issued by
Atkins Rail (RSSB) for the modification of the Mk2 WSP
to Mk1 operation.
A Mark 2 WSP Rack can now be fitted to a Class 313.
The C313 uses a Mark 1 WSP (97/2362, 97/2363) and spares
for these racks are scarce so by using the Mk2 WSP as a
donor which can then modified by XBR as a "black box"
replacement for the DMC rack a fully functioning "MK1
WSP" can be created.
This rack has all the functionality of the Mk1 rack and
it is expected that it will have the reliability of the
Mk2 WSP which is an obvious improvement when compared to
the Mk1 WSP.
The DMC rack (97/2362) is interchangeable between both
the DMC and RT positions on the vehicle simply by
removing the Slip Comparator (97/2513) so in fitting the
XBR DMC WSP original MK1 DMC WSP are free'd up for use
as stock for both the DMC (97/2362) and RT (97/2363)
positions.

Shunter Electronic AVR
Carbon pile regulators are yesterday's technology and
yet they still hang in there - or do they?
It is becoming increasingly more difficult and more
expensive to have the carbon piles replace - and how
reliable are they?
The XBR Shunter regulator for 08/09 90v and 110v
shunters is currently under production.
This has been used by many shunter operators and has
proven to be reliable in the field.

Automatic
Test Equipment for WSP- Depot Trials (08/08/11)
 
The continuing XcaliBR project to develop a
replacement Automatic test set for use on Southern
Railway's C455/456 fleet is nearing completion. The
software for testing the C313 WSP has been installed
and is undergoing final testing at XBR.
This project was initially conceived to be a
replacement for the existing WSP ATE and was for use
on the C455, C319 and C456 fleets at Selhurst depot
but it has now been expanded to include the Mark1 WSP
that is used on the C313 fleet.
Southern's working brief was that the equipment should
be "Ruggedised" to make it more reliable for depot use
than the equipment that it replaces.
The design includes a single plane motherboard onto
which all the other printed circuit boards are
mounted. this avoids the problems caused by the rack
mounted modules in its predecessor.
 The entire
test set can be trolley mounted for ease of use.
The prototype of this equipment has been returned to
XBR for upgrading to the production version after
several successful years service in the field.

Class
455 CLR Passes "Type Approval" (08/08/11)
Southern Railway have committed to replacing the
existing C455 CLR with the XBR CLR and have commisioned
two prototypes to replace the CLR on the C442.
The Current limit Relay that is used on the C455 is
notoriously difficult to set accurate enough to enable
two 455s to run as a set.
XBR were given the task of developing an electronic
version.
This prototype has passed all of the relevant EMC tests
and the Initial vehicle tests have been completed.
Current indications are that it is suitable for use on
the C442 so watch this space.
