Model railroad AccommodationAdhesive Weight

Adhesion factor
The ability of a locomotive to pull a heavy train without slipping.

Adhesion is the molecular attraction exerted between bodies in contact.
Mechanisms of Adhesion
Five mechanisms have been proposed to explain why one material sticks to another:
Mechanical Adhesion ...

Adhesion factor
The percent of the total weight on a locomotive's driving wheels that is available for traction; also called adhesion coefficient, it's the measure of how well a locomotive grips the rail.
ADM ...

Adhesion
The amount of pulling or retarding force a wheel is capable of exerting on the rail without slipping or spinning.

Add, to Couple car(s) to a train Adhesion Coefficient The ratio of tangential and normal force that exist between the wheel and the rail during motion.

Adhesion Coefficient (m) The ratio of the tangential and normal forces that exist between the wheel and the rail at standstill and during motion. The adhesion coefficient for rolling motion is usually referred to as m R. Generally taken as 0.3 to 0.

The condition of black rail is eliminated because of the LIMs ability to drive and brake the vehicle completely independent of wheel-to-rail adhesion.

See Rail adhesion.
Wheel Flange: The inner section of a wheel that rides between the two rails. The angle between the wheel tread and flange is often specific to the rail to prevent wheel climb and possible derailments.See Rail adhesion.

Adhesion - The frictional grip of the wheel to rail; Maintenance of contact between the wheel s and the rail.
Adhesive Weight - The total of the driving-wheel axle loads.

High adhesion locomotive axles were counted as 1 1/3 conventional traction motors, hence, a C40-8 or an SD-60 with 6 actual axles would be counted as 8 axles.

The paint on the joints prevents good adhesion and can be very hard to remove.
Using a small brush, simply paint the glue on the paint covering the joint to be attached.

stick and mount the canopy to the stick by placing the body over the top of the stick and pressing it onto the tape. This will allow you to paint the canopy without having to touch the piece, as oils from your hands can interfere with paint adhesion.
