    Default Merseyrail- Heavy Rail to Light Rail

    Merseyrail heavy rail rolling stock is in need of replacement. One approach is to replace gradually the existing heavy rail rolling stock with cheaper light rail rolling stock, similar to use on the London Docklands Light Railway. This would give more cars to a train, however in off-peak times only a few of these shorter, more economical to run cars need be used.

    A great advantage is that smaller light rail cars can negotiate tighter curves than longer heavy rail train cars. This entails tighter curves when extending Merseyrail, like out of the Wapping and Waterloo tunnels.

    On certain lines heavy rail dual power trains could remain, such as the proposed Wrexham to Liverpool Line when electrified.

    There is no logical explanation how that would 'give more cars to a train'. The number of cars to a train has no corrolation to the design or weight of them.

    You missed the point and I was not clear. Shorter Light-Rail cars would give more cars per train if the full platform length is used. Shorter cars means a train can negotiate tighter curves, which means train could come out of the Waterloo Tunnel and be on a tight curve to branch onto the Northern Line. Also to manoeuvre around the docks as in London's Docklands.

    Light-Rail cars also means trains could be much shorter on off-peak times but more frequent - using improved signalling systems of course.

    I thought the carriages were on bogies. How do shorter carriages make any difference.

    The existing long carriages have a minimum curve in which to roll through. Short London Dockland's Light-Railway style of cars are very nibble, negotiating very tight curves around Docklands.

    Liverpool needs more stations in the centre and inner-city around the centre to make it a true metro of frequent trains and people using it to get from district to district. Extending the Network The Wirral Loop was supposed to be used as a means of getting around the city centre. It failed as few use it for that. It would have been better if the old Wirral Line after James St at the now Paradise St junction, was tunnelled into the Waterloo Tunnel. The Link tunnel from Central to Moorfields would cross this at Lime St and large station cut here. Central Stn could have been done away with. The large Lime St station (the existing is under St. George's Hall)), could have had long moving walkways to various exits. One exit at the location of Central, another at Lime St Stn, One at Williamson Square, dale St, etc.

    The Wirral train would have run through the city centre, through Lime St underground, up the Waterloo Tunnel, a station at the Royal Hospital and onto St. Helens, or either way, north or south onto the Outer Loop Line.

    It would have been cheaper than boring the full Wirral Line single track tunnel.

    Below: The Paradise St Junction. Three tunnels Looking north. The old James St to Central Stn tunnel to the left (not used for passengers, only shunting trains) The other two are the Northern Line to Moorfields run in separate tunnels.


    Below the 1970s Wirral Loop and Link Tunnel plan. Alternatives to use either Wapping or Victoria/Waterloo Tunnels plan. The Paradise St Junction can be seen. The Loop line in green, does not run under Lime St Stn.

    So it can only be done with DLR type coaches.
