| Show RAILROAD SCIENCE A writer i in n one of the london scientific journals has some peculiar notions in renard regard to the effect upon railway traveling of the ear earths t hs rotation it is well known that as t the he earth revolves on it its s axis once in twenty tw enty four hours from west to east the velocity of any point on its surface is greater near ilear the equator and less further from it in the ratio of the cosine of the latitude thus according to this ratio the difre difference rence between the re relative I 1 a t velocity of the earth in surface motion at london and at liverpool is about twenty eight miles per hour and this amount of of lateral movement is to be gained or lost as respects the locomotive in each journey ll 11 u 1 according to the direction travee traveled d in f from rom one place to the other and in proportion to the speed will be the pressure against the sides of the rails I 1 which at a high velocity will give the engine a ten tendency deney to climb the rig right hand rail in each direction |
