a new tunnel for suburban trains?
/This week, in the newspaper Politiken, there was a short article on a proposal, that has been presented to the parliamentary transport committee, to consider the construction of a new tunnel, for suburban rather than for metro trains, that could form a fast link from the existing station at Hellerup, in the north part of Copenhagen, to the transport interchange at Ny Ellebjerg to the west of the city.
The new line would be over 8 kilometres long and journeys through the tunnel would be rapid because there would be few intermediate stations but these would link to the metro at strategic points.
Hellerup is a small municipality immediately north of the city and is already a busy and important interchange for suburban trains from the north but, from there, the trains run to Østerport, Nørreport, Vesterport and the central railway station through relatively narrow cuttings that date from the early part of the 20th century and from the central station curve on out through to Carlsberg and Valby or to Sydhavn and Ny Ellebjerg. All these stations are well-used interchanges and there are also smaller but also busy intermediate stations. It is a regular and relatively fast service but trains can be crowded and many of these stations are extremely busy and must be close to capacity.
Few people will travel regularly from Hellerup to Ny Ellersbjerg but a new tunnel would provide shorter and much quicker links through to alternative interchanges for joining the suburban train lines or the metro circle line at more appropriate points to get into the city or to get out to outer suburbs.
As proposed, on a new line through the tunnel, there would be just four intermediate stations ….. a station at Vibenshus Runddel - connecting to the new circle line of the metro and serving the national football stadium; a new and important station for Rigshospitalet and then new interchanges with the metro at Forum and Frederiksberg.
Trains would be short - like the metro train - and could be automatic, so driver-less, and could run every four minutes and, of course, trains would continue to run on the existing line.
This switching from train to metro or even to bus sounds complicated and frenetic but actually commuters know their routes and platforms and do most journeys on auto pilot anyway but, for other passengers, travel apps on mobile phones, updated in real time, show the best route and current arrival and departure times, platform numbers and the quickest route and electronic displays at platforms and on trains and buses now show arrival and connection times.
This is joined up planning. Planners and politicians are not resting on the laurels of what is being achieved with the construction of the new metro lines in the city but are already thinking about what has to be done next.
