Send message »An electric locomotive is a locomotive powered only by electricity. Electricity is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of three forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings; a third rail mounted at track level; or an onboard battery.

On railways, a given section of track is designed to support a maximum axle load. The maximum axle load is determined by weight of rails, density of sleepers and fixtures, train speeds, amount of ballast, and strength of bridges and earthworks. If the track is overloaded by ….
Send message »When the locomotive is placed on the track and power is applied to the track the locomotive will detect the type of control system being used and respond accordingly. Below is an overview of the 4 different systems. NOTE: You'll need to have the DCC/DCS 7.

Slow movemente (stars, stop ), and tad lines be used to control swinging of the loadA crane with or without a load shall not be traveled with the boom so high (it may bounce back over the cab)When rotating the crane, sudden starts and stops be avoided.
Send message »Some of these engine improvements include high-pressure common rail fuel injection systems, electronically controlled injector solenoids, and advanced turbocharging. While these improvements enabled engine manufacturers to meet Tier 2, and Tier 3 standards, in order to meet the more stringent Tier 4 interim and Tier 4 final regulations, exhaust after-treatment was required.

I'm pretty sure that the practice was common on many roads, in order to dress the flange area of the tire/wheel. Attempting to dress, i.e. remove material from, the tread are would be very, VERY tricky on a steam locomotive, since the diameter of ALL the drivers.

Send message »Excessive pressure may cause the boiler to violently burst, resulting in injuries and fatalities to nearby individuals, as well as extensive damage to the locomotive itself and nearby structures. At the front of the boiler is the smokebox, where exhaust steam is ejected into the chimney or stack, drawing the smoke and combustion gases through the fire tubes in the boiler and out the top of the chimney.
