Local press advises that Herts CC have given up the fight on a "terminal" due to gridlocked issues with the local (largely) housing plan. We await developments , if any. Obviously not a great time for some kinds of development.
For most St Albans residents, this is a lose, lose, lose solution:
1) The MML, the key rail link to London, which is already not far short of being maxed out, will be threatened by the need to accommodate decelerating and accelerating freight trains along the first full-speed length of line out of St Pancras. ISTR that NR didn't raise any objections over 10 years ago saying that they could absorb the additional traffic on the route. The local commuter group pointed out that in practical terms there was a problem so the developer was able to secure permission to run the facility as a road to road operation until a viable connection to the MML was built (if at all).
2) The road to road traffic would dump a continuous stream of HGV traffic onto the A414 between London Colney roundabout and Park Street Roundabout. This 2x2 lane dual carriageway is basically unchanged in layout since the M1/M10 was opened in 1959. It takes a proportion of the traffic from M1 J7 heading clockwise from M25 J22 and vice-versa. It also takes a considerable amount of the traffic from the M25 J21A to join the A1M northbound at J3 (and vice-versa). It also is part of an E-W link across South Hertfordshire from Hemel Hempstead to Hertford, and a local by-pass for St Albans. It is possible that the road will become unusable for much of the day as traffic in general increases.
3) By removing the opportunity to build on Radlett Aerodrome, it will be necessary to find room for another 2000 homes within the St Albans district area. For those that aren't familiar with the area, it will be extremely difficult and probably quite damaging to local amenities to achieve this.
So there we have it, a strategic railfreight interchange that will either worsen the rail services in the area or compound existing traffic problems,
and add to an already difficult residential land-use issue.
