It is true that, in regard to the last-mentioned of these three main principles, material changes have been brought about by the resort to electricity as a motive power; but this, after all, is an improvement in the means of rail transport rather than a complete change in the principle of transport itself; and, though electricity may supersede steam to a considerable extent, especially for suburban traffic, the resort to it is a reversal, in another form, to the earlier idea of motive power distributed from a fixed point, as originally represented by stationary engines, before the locomotive had established its superiority thereto.

In any case, the railway is still the railway, whatever the form of traction employed, and there is, after all, no such fundamental difference between an electric railway and a steam railway as there was between the railway and the canal, or between either railway waggon or canal barge and the carrier's cart travelling on ordinary roads. The question that really arises here is, not whether electricity is likely to supersede steam for long-distance as well as for short-distance rail traffic, but whether the railways themselves are likely to be superseded, sharing the same fate as that which they caused to fall on the stage-coach and, more or less, on the canal barge.

For the physical, economic and other considerations already presented, there is no reasonable ground for expecting much from the projected scheme of canal revival. When the country comes fully to realise (1) the natural unsuitability of England's undulatory surfaces for transport by artificial waterways; (2) the enormous cost which the carrying out of any general scheme of canal revival would involve; (3) the practical impossibility of canal-widening in the Birmingham and Black Country districts; and (4) the comparatively small proportion of traders in the United Kingdom who could hope to benefit from a scheme for which all alike might have to pay;—it is hardly probable that public opinion will sanction the carrying out of a project at once so costly and so unsatisfactory in its prospective results.

Still less than in the case of canals would any attempt to improve the conditions of transport on rivers—serving even more limited districts, and having so many natural drawbacks and disadvantages—be likely to meet any general advantage or to foster any material competition with the railways.

Developments in regard to road transport are much more promising—or, from the point of view of the railways, much more to be feared—than any really practical revival of inland navigation.

Dealing, in this connection, first with personal travel, we find that the main competition with the railways proceeds from (1) omnibuses, motor or otherwise; (2) electric tramways, and (3) private motor-cars.

An omnibus, whether of the horse or of the motor type, is the equivalent of the carrier's van or of the old stage-coach in so far as it has the complete freedom of the roads. The electric tramway, while having to keep to a certain route, and involved in greater capital expenditure by reason of its need for rails, overhead wires and power stations, may, if owned by a local authority, still be materially aided, directly or indirectly, out of the local rates. Thus the omnibus and the electric tramway may both be able to transport passengers at lower fares than the railways, which, as regards the municipal tramways, may even be called on to pay, through increased taxation, towards the maintenance of their rivals.

In London itself the motor-omnibuses have undoubtedly abstracted a considerable amount of short-distance traffic from the Central London Railway, which, however, still has the advantage in regard to longer distance journeys.

That electric tramways and motor-omnibuses have also diverted a great deal of suburban passenger traffic from the trunk railways is beyond dispute. But here the companies are seeking to meet the position (1) by operating their own suburban lines by electricity, giving their passengers a quicker transport than they would get with tramways or motor-cars stopping frequently, or held up by traffic repeatedly, on the roads or streets; or (2) by offering to town workers greater facilities for removing from homes in the inner to homes in the outer suburbs, if not in the country proper or even on the coast itself—in other words, to such a distance that they would naturally be dependent on the railway and the business trains that are now run thereon from the places in question to meet their special convenience.[[71]]

Of these two developments the former has not yet been generally adopted, whereas the latter is in full activity, and, in combination with the heavier local taxation which is steadily driving people away from London boroughs, is helping to produce results of much interest and importance.
