  1. A paved track on which road vehicles can be tested.
  2. A railway track for the purpose of testing trains.
    — Research would be facilitated if a test track of suitable length and characteristics for coach running tests at speeds up to "90 m.p.h.-plus" were on offer, as there are obvious difficulties in making available a regularly used main line for such purposes; but B.T.C. plans in this respect have apparently suffered under the economy axe.
