The lateral motion driving boxes can also be applied toengines having four-wheel trucks. In the ordinary design of 2-10-2 type locomotive, about80 per cent of the total weight of the engine is on the is therefore interesting to note the increase which has beenobtained on these new engines, as shown in the table: X. v.
