A view from the saddle- training for HGV drivers

This is troll science, right? You haven't factored the number of trucks required into your mpg figures:

hang on....

While they say that a train can carry 37 HGVs (good!)
Trucks = 7 miles per gallon, trains = 0.7 miles per gallon.
1 truck = 30 tonnes
10 trucks = 300 tonnes

37 trucks =
1110 tonnes at 0.7 miles per gallon (train)
vs
1110 tonnes at (7x37) 259 miles per gallon (truck)

Importantly, no cyclists are killed by left turning trains.
