>>1991837I don't think there's a link from the GWML to Marylebone, without going the super-long way around - meanwhile there's a convenient-ish link at Friars Junction, just west of the Old Oak Common construction site, that can get you to Euston or Waterloo ... I suppose if they were to use Waterloo they'd need to fire up the diesel engines, as there's no overhead power in that part of town, and thread ten-car intercity trains around London commuter trains
