[Reposted] Hammerson insisted anyone wanting TRAMS at BRENT CROSS must sign agreement not to oppose its planning application. Despite Barnet's subsequent corrupt 2010 planning consent, the idea will not go away...

(Barnet and Hammerson have complained about height clearance and catenary obstructions over the years at Brent Cross, and never supported investigation of trams or light rail.)

"Railway Gazette: The 21 CAF Urbos 3 trams used on the Midland Metro light rail line are to be retrofitted with batteries to enable catenary-free operation, West Midlands transport agency Centro announced on February 12, and four more trams have been ordered which will be supplied with batteries already fitted.

"This will allow catenary-free running on four planned extensions:

• Birmingham New Street station –Centenary Square extension scheduled to open in 2019, running through the architecturally sensitive Victoria Square with the 182-year-old Town Hall;
• Edgbaston extension from Centenary Square, through Brindleyplace and the underpass at Five Ways;
• Eastside extension between Moor Street Queensway and Digbeth High Street, where battery operation would avoid the need to lower the existing road under the West Coast Main Line and reduce the headroom required under the proposed HS2 station at Curzon Street;
• Wolverhampton city centre extension between the bus and railway station tram stops.

"West Midlands Integrated Transport Authority Chairman Councillor John McNicholas said catenary-free operation had been envisaged when the CAF trams were ordered in 2012, and the contract included provision for retrofitting. Urbos trams fitted with supercapacitors are used in Zaragoza and Sevilla, however, this technology was felt to be unsuitable for the steep hill in Birmingham’s Pinfold Street, while battery technology was not sufficiently developed when the order was placed.

"Negotiations are now underway with battery suppliers. The cost has not been finalised, but the Greater Birmingham & Solihull Local Enterprise Partnership will contribute £3·15m and industry association UKTram £1m. The batteries will be fitted on the tram roof and will be recharged from the overhead lines along other parts of the route. They are expected to require replacement at approximately seven-year intervals."
