Locomotive Standards And Rules

Standards

Locomotives run on this layout shall match all of the following requirements:

• Be equipped with Kadee or other knuckle coupler
• Be equipped with a NMRA compliant decoder
• Be able to negotiate a #5 turnout
• Have RP-25 wheels, that are in gauge

Locomotives should meet the following requirements:

• The address should be the locomotives road number and use the appropriate address size (2 Digit or 4 Digit)
• Decoders should be able to accept Advanced consisting
• Locomotives should be complete. (No undecorated units or units without handrails)

Other Rules

Most of the following "rules" are derived from various documents. They are intended to make operations more interesting. They include rules that pertain primarily to consisting of diesel electric locomotives. As I don't have a large number of electric locomotives they will almost never be found in a consist. Noted exceptions are listed where they are applicable.

Mixed Power

With the exception of designated trains, no more than the equivalent of 24 conventional axles may be operated under power on the head end of a train. (High-Adhesion axles are equivalent to 1 and 1/3 conventional axles and AC traction axles are equivalent to 1 and 1/2 conventional axles) The following table shows examples of mixed power. (32 powered axles for solid commodity trains. (unit trains))

Dynamic Brakes

If a consist includes one or more units equipped with standard dynamic brakes, not more than 202,000 pounds of dynamic braking force may be used on the head end of the train. If all of the units are equipped with Extended Range or Extended Range High Capacity dynamic brakes, not more than 180,000 pounds of dynamic braking force may be used on the head end of the train. (This rule is just simulated, and doesn't pose any true operational considerations. Units that cause the train to exceed this limit will be assumed to have had the dynamic brakes cut out.)
