Trackwork
# The mainline tracks shall have 0% grade and a constant elevation of 0 inches (except on the permanent layout). Other tracks have no grade or elevation restrictions.
# Curved tracks on corners shall have a minimum easement of 1” of straight track at each end to eliminate derailment problems. (See Fig. 3a)
#The spacing of mainline track is 2 inches centerline to centerline at the end of a module, and must have a 2 inch minimum spacing throughout. All other tracks have a 2 inch centerline Eastbound mainline track must be 5 inches at centerline from edge of module.
# Mainline tracks must be code 100 nickel silver and can be either pre-assembled on plastic ties or hand laid on suitable wooden ties. Other tracks have no restrictions.
# Turnouts used on the mainline for crossovers or passing sidings must be Peco “long” at the minimum. For sidings off the mainlines, there are no restrictions on turnout types or size.
# The only uncoupler that may be used on the mainline is the Kadee electromagnet type mounted under the track. Other tracks have no restrictions.
# The rail ends shall be securely fastened to the roadbed for positive alignment. Provide access to all trackage for maintenance purposes.
# Mainline track shall end 3 inches from each end of the module. Two 6” Atlas Snap Track modified sections shall be used to connect the mainline tracks together. These connecting track sections are adjustable to help with warpage.
# Mainline switches ending 6 inches from the end of a module require a 3 inch track section be added to the end of the switch. The switch and the 3 inch track section must be securely fastened to the roadbed to accommodate the 6" Atlas Snap Track jumpers between modules.
# Insulating gaps shall be used at all crossovers and at any track connection to either of the mainline tracks. The location will vary with the type of control and the individual design of the trackage of the module. If insulating rail joiners are not used, the cut rail shall be held in gauge with epoxy or equivalent cement and the gap filled with insulating material.
#Crossover switches should be of the trailing point installation wherever possible on modules. (See Fig 6)
# The corner module curves shall be of 38” radius for the inner (Westbound) track and 40” radius for the outer (Eastbound) track. Transition curves may be used in place of the circular arcs.
Use of the “bent stick” method to establish a template for corner module curves is recommended.
# The sidings off a curved mainline shall be accessed only with the use of a Peco curved turnout. The long minimum applies to these turnouts.
