Note 644 — VIII CONCLUSION

"The cost of the service of transport for any given commodity cannot, under the varying conditions of railway operation, be even approximately calculated. The first insuperable difficulty is the division of the expenditure for any given work. Though railway economists have endeavoured, by means various and ingenious, to allocate the different items of railway expenditure, they have been unable to determine such a relatively simple matter as the division between passenger and goods traffic, and though estimates have been formulated, many of the charges have been allocated to one head or another by arbitrary decision, and not as a result of positive knowledge."—Railway News, London, 6th September 1913, p. 396.
