LondonUnlocked featured an article some weeks ago about Poma's MiniMetro system, which we profiled as a possible project for TfL and the Mayor's office to look at more closely. Poma are perhaps better known for installing custom cable metro systems around the world. Whilst the majority of their projects are not city based, they do have experience in this area and have worked with London's authorities before, most notably in supplying the pods for the London Eye (below):
Their fixed cable systems have been installed in New Orleans and Medellin, Columbia, are very successful small-footprint designs. The schemes are environmentally friendly, easy to set up, and provide fast travel over both long and short distances.
These projects are entirely compatible with existing mass transport systems and, as in the case of Medellin, have been built on an existing underground station, easing commuting times. Wheelchair friendly, quiet, and emission free, these are modern solutions to modern transport problems.
TfL and the Mayor need to look at the possibilities of projects such as these, especially with the testing ground of mass public transit that the 2012 Olympics will be.
