would seem that a good length of railplane 

 track would be equally expensive in this 

 respect. 



Again, the inventor is ready with an 

 answer; he says that the whole of modern 

 progress is to obtain, first, long-lasting 

 enamels and paints, secondly, efficient 

 methods of spraying the paint, and, thirdly, 

 of incorporating in the steel something 

 which will make it rustless such as chronium, 

 although the latter would be out of question 

 at the moment from point of cost. 



He does admit, however, that the painting 

 of the track would cost almost as much as 

 its running. A moderate system gives this 

 paint work as costing 200 per mile per 

 annum, or with other details such as 

 signalling stations and so on it would 

 possibly run to 300 per mile per annum. 



Each car would require only one attend- 

 ant, the entrance and exit gates being 

 automatically controlled. The inventor 

 contends that here alone there would be 

 substantial savings in wages costs.
