The transport costs to the community were not necessarily what any individual might pay, but what it cost to produce the transport, because that sum total of costs had to be paid in some way. It was only a matter of distribution. It might be paid by the users or the taxpayer. The cost in respect to one commodity might be apparently paid for by the charge on another commodity, but the point he was making was this: that the sum total that had to be paid, whether by way of railway charges or otherwise, was measured by the cost of producing the transport.
“Last year the railway management would have squared the railway accounts, including developmental costs, at 2.86d. per ton mile average. Could any motor carrier produce transport by motor of the commodities of this country at that figure? The actual revenue came to 2.41d. per ton mile; the balance required was .45d.—less than ½d. per ton mile—to square the ledger.”—Mr. H. H. Sterling.
