The introduction of curves in railways, unless theirradii be very great, has hitherto been considered unsafe,and the cost of the construction of railways is, under ;certain circumstances, greatly increased by this con- isideration. To give to a train the power, under certaincircumstances, itself to change that rectilinear motion towhich by the first law of motion it tends, into a motionwhich shall cause it to follow any curvature it may beconvenient to give to the line, would be to afford newfacilities for the construction of railways.
Our colleague, M. Arxoux, who, as a member of theSub-Jury A., on Carriages, was placed out of the numberof competitors for medals,* has attempted the solution ofthis problem on the railway from Paris to Sceaux , and aworking model of one of his trains is exhibited in theFrench Department. On this railway there is a zigzag,the radii of whose curves vary from 1G5 to 200 feet,
* As the labours of the Sub-Jury for carriages were con-ducted independently of the principal Jury, the exclusion
