| "If the new Overground service to Brentford has the same frequency as the existing Overground, then that is 16 trains per hour in both directions and I can't see how they could keep Bollo Lane and Churchfield Road open with those frequencies." I investigated that very point when I was working with LBH on the proposal for a Crossrail branch to Hounslow. This is what our report said: "By comparison, the busiest level crossings in the London area are thought to be those between Barnes and Richmond, including B353 Manor Road and B351 Sheen Road (at Mortlake Station). These currently handle peak frequencies (counting both directions) of up to 19 trains per hour. Vine Road in Barnes has a pair of level crossings which together handle 25 trains per hour, though with less traffic than Bollo Lane. Observation of the Manor Road crossing during a recent evening peak showed that the crossing gates were closed to road traffic for approximately 50% of the time, but that despite this, the flow of motor vehicles was at a rate of more than 750 per hour. These figures suggest that Bollo Lane, with almost certainly lower numbers of vehicles, should handle the combined total of 16 trains per hour without serious problems." That was written 10 years ago (crumbs, doesn't time fly!), and maybe road traffic volumes have increased since then. But between 8 and 9 a.m. we now have 21 trains at Manor Road and Mortlake, and a total of 29 trains over the pair of crossings in Vine Road. So 16 per hour at Bollo Lane or Churchfield Road is feasible, I reckon. |
