Table XIV.—Annual Cost of Repairs of Carriages and Wagons in Pounds.

For 340, 477, and 681 trains per annum, moving the same traffic as 500, 700, and 1,000 trains per annum, the same annual costs for maintenance of way and carriages and wagons can be used, because the number of car miles will be the same ; and because the total gross ton mileage will be nearly the same, the cost of maintenance of way and carriages and wagons should also be the same. Combining the results of Tables IX., XII., and XIV., the total working-cost of these lines is obtained. This is given in Table XV., which includes £800 per annum for ventilating the long tunnels of lines A and B.

Table XV.—Cost of working, Otira to Bealey, in Pounds.

Adding interest on cost of construction at 3£ per cent, to the total working - costs of Table XV., the total annual charges, which form the true basis for the economic comparison of these lines, is the final result given in Table XVI.

Table XVI.—Total Annual Charges in Pounds.

It will be seen, by comparing the above table with that contained in my report of February last, that the differences between the one and the other are not very material, and that in any event they are not such as would warrant any change of the recommendations made in the report mentioned. I have, &c, V. G. Bogue The Hon. W. Hall-Jones, Minister for Public Works, Wellington, N.Z.
