Are trains the most efficient form of transportation?

It is very true that when moving on flat ground in a straight line, trains on steel wheels and rails are the most efficient form of transportation. Rolling on steel rails reduces rolling resistance and traveling at slow speeds (compared to jet aircraft) reduced the force of air resistance.

A standard lightweight, moderate-speed bicycle is one of the most energy-efficient forms of transport. Compared with walking, a 64 kg (140 lb) cyclist riding at 16 km/h (10 mph) requires about half the food energy per unit distance: 27 kcal/km, 3.1 kW·h (11 MJ) per 100 km, or 43 kcal/mi.

Freight trains are several times more energy-efficient than trucks, because 1) the rolling resistance of the steel wheels of trains is lower than that of truck tires on the road, and 2) trains encounter less proportional wind resistance than trucks since a train car is partly shielded from the headwind by the car in ...

If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.

Greenhouse gas (GHG) emissions are directly related to fuel consumption. According to EPA data, freight railroads account for just 0.5% of total U.S. GHG emissions and just 1.7% of transportation-related GHG emissions. Moving freight by rail instead of truck lowers GHG emissions by up to 75%, on average.
