In 1902 the company took over asingle-track line which had been built in 1901 between Mingoand Steubenville, and which took a very circuitous and hillyroute over the mountain.

The plan and profile ofthis old route are shown on the drawings on page of the extraordinary curves and grades encounteredon this line are evident from these diagrams. On this hill line the company has maintained a 20-minuteschedule. In order to enable it to perfect a through routenow nearing completion between Wheeling and Steubenville,of which the stretch between Mingo Junction and Steuben-. VIEWS ON OLD LINE TO STEUBENVILLE, SHOWING STEEPGRADES AND SHARP1 CURVES ville is an important link, and to secure a material reductionin running time, the company has built a cut-off betweenMingo Junction and Steubenville and will use this shorterline as a substitute for the hill-line for all travel betweenthese points. The plan and profile of this cut-off are shown on page 547 in comparison with the hill-line, and thesaving brought about is strikingly revealed. The distanceof the cut-off is miles, as against miles, which is thelength of the hill-line between the same two points, makinga saving in distance of miles. The reduction in gradesand curves is also made clear by these comparisons. In the building of the line between Mingo and Steuben-ville, up to Sept. 1 unclassified excavation, that is to say, rock,coal and earth, amounted to 82,233 cu- yds.; masonry, in-cluding rubble and concrete, 9105 cu. yds. The estimatedamount of excavation yet to lie made amounts to 15
