1 rail car = 3 to 4 truckloads.One rail car can hold up to 220,000 lbs of product, which typically equals 3 to 4 truckloads. This rule of thumb depends on the type of product being hauled, but it works for the vast majority.

There is currently no federal regulation limiting the number of cars in a train or number of crew needed. Long trains often crash or derail in the simulator, said Iowa-based Railroad Workers United officer Jeff Kurtz, a locomotive engineer for 41 years who retired in 2014. They're a new phenomenon.
The locomotive connects the bogies well above the center line of the loco wheel. When the loco pulls the frictional force (rolling) times the bogies total weight makes the rear wheels of loco to exert more vertical force (due to moment arm) and this adds up to the loco dead weight.
Pulling loaded coal cars? Once the train is rolling, an engine with 110,000 lb tractive effort should be able to maintain 11-12 mph with at least 200 cars-- maybe 300 or more.
The heavier a locomotive is, the better the coefficient of adhesion, and the better the locomotive can transmit power to the rails without wheel slippage.
To help the wheels stay on the track their shape is usually slightly conical. This means that the inside of the wheel has a larger circumference than the outside of the wheel. (They also have a flange, or raised edge, on the inner side to prevent the train from falling off the tracks.)
They rely on precise track. Rolling resistance of nicely round steel circle on nicely smooth steel rail is negligible to rubber-tarmac contact. The other thing it utilizes is the locomotive weight. The contact pressures in the wheel-rail contact are very high and they use sand to increase the traction.
“It comes out in shreds as small as your fist. The scrap steel from BART cars is sold to mills to create new products like rebar. The aluminum and copper are shipped to smelters and foundries to make new aluminum airplane and car parts, and copper wiring for home appliances and electronics.
One railcar can hold the equivalent of roughly four truck loads. Additionally, one train can haul the equivalent of over 400 trucks. In order to move 400 trucks on the road, it would require 400 drivers compared to the two engineers that could run one train.
