The Track Feeder Switch (TFS) is required to bring isolations of the 750V DC conductor rail into line with the requirements of the Electricity at Work Regulations 1989.
The TFS isolates the live conductor from its sources of energisation (Electricity at Work Act Regulation 12) and securely protects against inadvertent re-energisation from any source (Electricity at Work Act Regulation 13) by being connected to the negative pole of the supply via the bonding switch.
Currently being installed on Merseyrail

L.C. Switchgear are supplying Controlled Track Switches (CTS) and Negative Short Circuiting Devices (NSCD) for CP5.

Work on Ealing Common is already underway and is first for completion in 2015, with the Upminster depot revamp expected to be completed by 2016.

The new Williams Way Substation has been built to supply the new Three Bridges depot. 4kA Bonding devices supplied by LCS are on the outgoing feeds to the depot which can be used to bond the outgoing supplies for maintenance.

LCS is providing the shore supply system from the Road Track Feeder Isolators to the Road Contactor Suites, feeding the Overhead Tow Trolleys for the extended depot. The extended depot roads can take the extended 3 car DLR trains without uncoupling to fit into the depot. The new Contactors provide safe isolation and bonding for the depot maintenance.

LCS designed Integrated Circuit Breaker Contactor & Motorised Isolator suites provided the automated changeover from DC to AC traction systems.

LCS is just starting to supply manual off load / fault make Depot Switches and motorised and manual Tunnel Switches for the Jubilee, Northern and Piccadilly Lines.

LCS provided the maintenance and 4 hour response cover for the Controlled Track Switches (Mk3) (CTS) and the LCS2 Supply Disconnectors and the Road Contactor Suites.

LCS developed and subsequently supplied a number of fully compliant remotely operated units to Network Rail.

Substation 5A and 7 switchgear for the depot and fan upgrades to Wednesbury Depot were supplied by LCS in early 2013 with Substation 9 to follow at a later date.

L.C. Switchgear are supplying Controlled Track Switches (CTS) for CP4, which were the same as the Controlled Track Switch (CTS) products used on the Power Supply Upgrade and the Channel Tunnel Reinforcement projects.

LCS is currently supplying manual off load / fault Make Depot Switches and motorised and manual Tunnel Switches for the Metropolitan Line.

The East London Line required reliable switchgear with a proven track record for its AC/DC Test track and power configuration of the roads at New Cross Depot.

In conjunction with the works leading up to the 2012 Olympic Games, the North London Line from Willesden High Level to Stratford via Gospel Oak, is being upgraded with enhancements to the Signalling, Permanent Way, and Civil Engineering and Telecommunications systems.

Road contactors provide the 750V DC supply to Trolleys & Pedestals which provide the shore supply for the rolling stock.

LCS has recently completed an order to supply motorised and manual Tunnel Switches for the VLU.

At Ashford the requirements for train movements from an Earthed Traction System to a Traction Negative Traction System involved switching the supplies to a Buffer Zone between the two.

Completion of the CTRL Spark Gap resistor project was done in a very short lead-time.

The Depot improvement scheme required switchgear to provide a totally safe solution to Road Switching and Train Stabling whilst ensuring maximum train movements on London Underground routes.

LCS provided the shore supply system from the Controlled Track Switches (Mk3) (CTS) and the LCS2 Supply Disconnectors, through to the Road contactor Suites, to Trolleys & Pedestals (Supplied by others) to the train.
