Consultants review BCR for Ellon

The benefit cost ratio for restoring the railway line between Ellon and Aberdeen has been subjected to a sensitive test review that accommodated a number of changes and assumptions.

These included:

  • Revised growth rates
  • Journey times for cars/buses
  • Car Parking rates
  • Induced trips
  • Removal of costs to double track tunnels north of Aberdeen railway station
  • Depreciation of rolling stock
  • Value engineering reduces costs
  • Reduce optimism bias figures

Although they substantially improved the BCR from the initial 0.28, the models did not achieve a ratio above 1.
