In operating the three-engine train eastbound, it is necessary to maintain the Deer Park helper, using about 4,300 pounds of coal per trip. The coal consumed by the road engine is also increased by working the single engine harder from Grafton and Hardman and across the glades, all of which counterbalances any saving that the three-cngine train might make.

The coal consumption per 100 ton-miles, assuming the same number of trains each way, with the one-engine and two-engine train operation, was 28.72 pounds west and 21.17 pounds east, or an average of 24.9 pounds.

Similarly, with the two-engine and three-engine train operation the coal consumption per 100 ton-miles was 27.59 pounds west and 21.84 pounds east, or an average of 24.71 pounds, showing no appreciable difference in the coal consumption between these two methods of operation.

Observations of Operation During the Test On Tests 15, 19, 21 and 23 with three engines, trains were cut about thirty cars from the head end and advanced to Newburg, where the road engine took water. The two helpers brought the balance of the train forward. This movement required on an average of 3 minutes at Hardman and 14 minutes at Newburg.

On Test 17 the train was cut at Hardman, but instead of advancing as in the above tests, the helpers were cut in and the entire train advanced to Newburg, where the road engine took water. This movement required 15 minutes at Hardman and 14 minutes at Newburg or about 12 minutes longer than the first mentioned movement.

In making the fill-out at Rinard, it required about 40 minutes, incl:ic!ing inspection of train.

At Bond it required approximately 20 minutes to inspect train, but on test 19 it required 1 hour and 20 minutes, part of the time due to broken knuckle in rear of train and then being held to wait for singleengine train to be inspected and allowed to leave ahead of the test train.

After making the second round trip, the engineer reported Engine 7133 needing flues cleaned and other repairs. This work was not done until the fourth round trip. It developed that there were thirteen large superheater flues stopped up and a number of smaller ones. On the last round trip, Test 23, the coal consumption was considerably better.
