XBR Have reviewed and amended their QMS to the new international standard. Our transition date is 12/02/18.


XcaliBR ATE for Mk3 Coach WSP has new prototype HST Variant Fitted

XcaliBR ATE Wheel Slip Protection test Equipment. This is the latest incarnation of this equipment. It not only has the capability for testing C455, C456, C319 and C313 WSP, it now has the capability to test Mk3 Coach WSP and this one in the photo is very special as it contains prototype hardware and software to enable it to test HST power car WSP


The XBR automatic WSP MK1 and Mk2 test equipment is currently being adapted for use on Mk3 Coach WSP with a view to use on the HST power car.

Vehicle Sequence Test Module For Mk2- Mk1 converted WSP

Mk2-1 wsp
                  vehicle sequence test moduleThe C313 vehicles need to to be sequence tested and to do this a module that fits in place of the relay module and enable the operator to mimic operations of the WSP whilst the vehicle is stationary was deveolped.
This module does not fit in the Mk2-Mk1 converted WSP so a similar module with all the same functions was created. This fits in the Mk2 rack in place of the Relay and timer modules

16x Headlamp indicator Panel- Reverse engineered

Our customer found themselves with too few spares and unable to purchase new from the original supplier. XBR were able to construct a version of the original from a sample that had been supplied.
The sample was sent to us when the vehicle entered the depot and we took the relevent information from the sample and returned it in time for the vehicles departure from the depot.

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.

08/09 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.

XcaliBR Automatic Test Equipment for WSP- Depot Trials (08/08/11)

XcaliBRXcalibr ATE Facebook

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.

                    motherboardThe 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.
