For the bus network operated by Mid Essex Transport (MET), see Mid Essex Transport.

A Metro service is characterised as a high frequency, high capacity urban rail network, often electrified, and often operating on independent (or pseudo-independent) infrastructure. Parallels can be drawn with the French RER or German S-Bahn networks. Metro systems are generally differentiated from Light Rail networks by their use of heavier infrastructure and rolling stock, potential for interaction or sharing of Mainline Rail infrastructure (although systems such as GMAX and ntram are blurring this), and higher overall speeds and capacity. Metro networks generally share common local branding, some with colour coded routes akin to that on the London Metro

Metro services can be operated by the Mainline Rail companies, Local Transport Company, or sometimes a combination of the above.

Metro systems in Great BritainEdit

Strathclyde Regional(Scotland)Edit

Operated by Glasgow Corporation Transport and Scotrail

Largest suburban rail network outside of London. Heavily electrified and mainly operating on it's own infrastructure. Includes the unique Glasgow Subway, operating in a loop underneath the city centre..

Tyne and Wear Metro (Newcastle)Edit

Operated by Northern Trains

Substantial 750v 3rd rail/25kV overhead operated system based upon the "Tyneside Electrics" rail network

Merseyrail (Merseyside)Edit

Operated by Northern Trains

This 750v 3rd rail/25kV overhead operated system links the Wirral to Liverpool under the Mersey, mostly operating on reserved track.

GMAX (Greater Manchester)Edit

Operated by Northern Trains and GMT

25kV overhead electrified system, with some DMU operation and track sharing with GMT operated GMAX 1 "heavy" Light Rail line.

WYnet (West Yorkshire)Edit

Operated by Northern Trains

Metro network focusing on Leeds and Bradford. Partially electrified, with limited reserved infrastructure

SYNergy (South Yorkshire)Edit

Operated by Northern Trains

Diesel operated network utilising the rail network of South Yorkshire.

LeapWM! (West Midlands)Edit

Operated by Midland

Ongoing electrification at 25kV overhead and infrastructure works means that LeapWM! is moving towards an EMU operated metro network operating on generally reserved infrastrucutre.

Valleylines (South Wales)Edit

Operated by WalesRail

Self contained network operating relatively high frequency DMU services in the Cardiff Valleys. Potential to be upgraded to a "full" metro under the SWIFT proposals by 2012.

AvonTransit (Bristol and Avon)Edit

Operated by Deluxe Great Western

Small DMU operated meto network based on Bristol Temple Meads station. Proposals exist to convert some routes in "Karlsruhe" style tram-metro operation.

Network London (Greater London)Edit

Operated by Network London, NeVida Eastern, South Coast Trains and GNEX

One of the largest metro networks in the world, Network London encompasses the heavy rail inner suburban network operated under contract, the DLR, and the London Metro. There is a fair amount of infrastructure sharing between non-LCT heavy rail, LCT sponsored heavy rail, and Subsurface and Deep level London Metro services, blurring the distinction between varying modes.

Proposed metro networksEdit

Lothian Rapid Transit (Edinburgh)Edit

Electrified heavy rail metro network utilising cross city rail routes, as well as the South suburban line and branches to Livingstone, etc.Derby

SPRINT (Southampton and Portsmouth)Edit

Hybrid light rail/metro scheme running the length of the conurbation, including a tunnel underneath Portsmouth Harbour.

DANtrans (Derby and Nottingham)Edit

Rough proposals for an enhanced Light Rail/metro network covering much of the Derby/Nottingham East Midlands conurbation.
