SUMMARY OF STATEMENTS OF L.& N. AND E.T., V.& G. RAILWAYS.

The mileage changed of the L&N. and E.T., V.& G.
systems combined aggregates                         3,622 miles. 
The total cost of these two roads.                     $331,492.59
Or an average per mile of                                    91.52
Total miles changed was about                        14,500 miles. 
Which would give total cost, at same rate.              $1,327,040

We should really add to this a large sum for the great number of new locomotives which were purchased to replace old ones, that could not be changed, except at large cost, and which, when done, would have been light and undesirable.

Upon the basis of the work done upon the L. & N. and E.T., V. & G. systems, which, combined, cover about one-fourth the mileage changed, we have made the following estimates, which will, perhaps, convey a better idea of the extent of the work than can be obtained in any other way: 

Miles of track changed, about                               14,500
Locomotives changed, about                                   1,800
Cars (pass, and freight) changed, about                     45,000
New axles used, about                                        9,000
New wheels used, about                                      20,000
Axles turned back, about                                    75,000
Wheels pressed on without turning axles, about             220,000
New brasses used, about                                     90,000
Kegs of spikes used, about                                  50,000
Cost of material used, about                              $600,000
Cost of labor, about                                       730,000
Total cost of work, about                                1,330,000
Amount expended on equipment, about                        650,000
Amount expended on track, about                            680,000
Amount expended on track on day of change in labor, about  140,000

The work was done economically, and so quietly that the public hardly realized it was in progress.  To the casual observer it was an every day transaction.  It was, however, a work of great magnitude, requiring much thought and mechanical ability.

That it was ably handled is evidenced by the uniform success attained, the prompt changing at the agreed time, and the trifling inconvenience to the public.—­Jour.  Assn.  Engineering Societies.
