A locomotive travel around a curve of $900$ m radius. If the horizontal thrust on the outer rail is $1/60$th of the locomotive$$s weight, determine the speed of the locomotive $($in km$/$h$).$

NOTE: The surface that the rails are on may be assumed to be horizontal and the horizontal force on the inner rail may be assumed to be zero. Take g as $9\mathrm{.}81$ m$/$s$2.$
