A roller chain connected the transmission to the rear axle. Timken roller bearings, 16-inch (410 mm) insulated wheels, and cast iron four-wheel brakes, were standard, adding up to a weight of 895 pounds (406 kg) without a cab. The 57W contained an air-cooled Wisconsin 4-cycle 1-cylinder motor, rated at 9.2 horsepower (6.9 kW).
No. 4070 was last assigned by the GTW to the "Oxford gravel run" in the Cass City Subdivision, where it pulled gravel and limestone trains between Pontiac and Oxford, Michigan. [ 1 ] [ 2 ] [ 5 ] No. 4070 was retired from revenue service on March 29, 1960, after it pulled its final revenue train from Pontiac to Durand, and the GTW completed ...

An axlebox, also known as a journal box in North America, is the mechanical subassembly on each end of the axles under a railway wagon, coach or locomotive; it contains bearings and thus transfers the wagon, coach or locomotive weight to the wheels and rails; the bearing design is typically oil-bathed plain bearings on older rolling stock, or roller bearings on newer rolling stock.
Route availability for a vehicle (locomotive or wagon) is generally based upon its axle loading. That is, how much of the laden weight of the vehicle is distributed on each axle. The more weight on each axle, the higher the RA number, and the more restricted the vehicle is. For wagons it is normal to have different RAs when running empty and full.
By 1837, Michigan had the beginnings of a railroad network, but one with which both the government and the people were dissatisfied. In the first seven years of railroading in Michigan (1830–1837), the Michigan Territorial Council approved charters for 23 private railroad companies. Of these, only five completed and opened lines, and then for ...
Heavier rail can support greater axle loads and higher train speeds without sustaining damage than lighter rail, but at a greater cost. In North America and the United Kingdom, rail is graded in pounds per yard (usually shown as pound or lb), so 130-pound rail would weigh 130 lb/yd (64 kg/m). The usual range is 115 to 141 lb/yd (57 to 70 kg/m).
A train wheel or rail wheel is a type of wheel specially designed for use on railway tracks. The wheel acts as a rolling component, typically press fitted onto an axle and mounted directly on a railway carriage or locomotive , or indirectly on a bogie (in the UK), also called a truck (in North America).
