SPEEDOMETER CHECK 1 Km, or 10 marker posts on a motorway, should take
55.9 seconds at 40 mph, 44.7 seconds at 50 mph and 37.3 seconds at
60 mph. Preferably measure over a longer distance.
MILEOMETER CHECK 1 Km (10 marker posts) equals 0.6214 miles. At least
10 Km is needed for any reasonable verification.
To help you with your selection the list below suggests a target minimum engine
power to aim for in relation to train weight. The first column shows car kerbweights,
the second a caravan weighing 85% of that kerbweight, and the third the bhp of a car's
engine that will be needed to produce 40 bhp/tonne of train weight. Obviously a
heavier caravan affects these figures.
