Thereis a 58-foot grade and several sharp curves in thissection. The advantage of the ample weight on drivingwheels is seen in the fact that with 190 pounds ofsteam and the reverse lever in full gear the wheelsdid not slip though sand was not used ; the rail,however, was in very good condition. The ad-vantage of the great heating surface is seen in thefact that in the heaviest work referred to the popvalves were blowing and the fire door was keptopen. This heating surface is sufficient to take upthe heat, while the greatest amount is being gen-erated without raising the smokebox temperature. Plan and Elevation torn. T esprings are of the elliptic pattern and from the front ele-vation of the truck it will be seen that the springs may be removedvery easily. The spring plank is a 12-inch channel with woodenfilling piece. The design of the truck is an unusually strong one,which compares very favorably with the other features of theengine. These engines are to be used on the Galena and Iowa divisionsrunning between Chicago and Council Bluffs. The larger num-ber of them will be used on the Iowa division, where the gradesare heavier than those of the Galena division. The engines aredoing excellent work. They have about 20 per cent, more haul-ing capacity than the best 19 by 24-inch engines on the road, andwhile no attempt has been made to ascertain their maximumcapacity, they have shown themselves to|be able to pull 1,138 tons,of which about 80 per cent, was in empty cars, while the rating of of Tender Truck, to an unusual extent.
