Conductor and brakemen.
Wear of cars.
Suppose we have to move 1,000 tons per day over any road. If we do it by one engine and 100 cars, the whole cost will be
| One Engineer | $2.00 |
| One Fireman | 1.50 |
| One Conductor | 1.75 |
| Four Brakemen | 5.00 |
| $10.25 |
And if we move 1,000 tons by ten trains of one hundred tons each,
| Ten Engine-men at | $2 | $20.00 |
| Ten Firemen at | 1½ | 15.00 |
| Ten Conductors at | 1¾ | 17.50 |
| Ten Brakemen at | 1¼ | 12.50 |
| $65.00 |
Difference of salaries in favor of the heavy train, of $54.75.
As the whole weight upon the drivers must be the same to move a given load by either method, the only difference in weights of engines will be that upon the truck. To lead well a truck must have five tons upon it. The whole weight upon ten trucks is, then, fifty tons, and that upon one, five tons, which leaves an excess of forty tons to be daily carried over the road by the small trains. The heaviest freight engine will not cost over $15,000; the cost of an engine to draw one hundred tons cannot be less than $5,000.
10 × 5000 = 50000 less 15000 is $35000. 6
100 of 35000 is $2100.
Add to this five times as much fuel used in firing up and standing with steam up, ten times as much oiling, cleaning, and repairing, ten times as much engine house and shop accommodation; also that the cars in frequent trains are much less loaded than in seldom ones, increased delay and chance of accident from increased number of trains, and estimating all of them at $170.00 per day, (the cost of the large engine being assessed at $30 per day, and that of each of the small ones as $20, the daily difference is $170,) and we have, as the whole daily increased cost of working ten small over one large train,
