The major new extension of the Metro in Copenhagen - the circle line round the historic centre - will now open on 29 September.

Above is the important new station at Trianglen at the south-east entrance to Fælledparken. It shows that much of the new hard landscape in place but the planned avenues of trees along each road edge are still to be planted and architectural features - such as the glass pyramids that will throw natural light down onto the platforms - are still to be installed.

Most of the new stations are at about this stage of completion above ground but the main reason for delay appears to have been caused by late delivery of the trains and the postponement of mechanical, electrical and safety testing.

Photographs of the station platforms and various designs and the different and specific colours for tiling, appropriate for the particular neighbourhood, have been published in some newspapers and show not just different and specific schemes for each station but mark a clear departure from the consistent design and the concrete finish of the existing stations on the first two metro lines that were constructed at the beginning of the century.
