OPERATING AGREEMENTS OF THE

NORTH TEXAS T-TRAK MODULAR RAILROAD CLUB

PLANO, TEXAS

Purpose: The purpose of the North Texas T-Trak Modular Railroad Club (the Club) shall be to foster the enjoyment of N-scale model railroading while promoting the T-Trak modular system.

Membership: Active membership in the Club shall be defined as ownership of one or more T-Trak modules, regular attendance at Club meetings and other functions, and acceptance of these Operating Agreements. Collateral membership is open to anyone who indicates an interest in T-Trak, but is unable to perform as an Active member. Geography or any other limiting factor shall not restrict membership.

Meetings: Regular monthly meetings shall be convened at a time and place agreed to by the Active members. Other meetings may be held as deemed necessary for the efficient conduct of business. Any meeting may be canceled or postponed as circumstances dictate.

Leadership: There shall be no officers or Board of Directors for the Club. The majority of Active members present shall decide all issues affecting Club operations.

Finances: There shall be no dues associated with either class of membership. Any monies earned through the efforts of the Club shall be dispersed as decided by the Active members. At least one Active member shall be charged with the responsibility of accounting for any monies held into the future.

Amendments: Any change to this document may be made with the agreement of at least one half of all Active members.

Adopted: November 9, 2004

Addendum #1 - T-Trak Module Guidelines

Preface: The purpose of this addendum is to set out, in simple and straightforward language, a basic outline for the construction, track placement, and wiring of our T-Trak modules. Following these guidelines will insure both mechanical and electrical interface when joined together with modules within our own group as well as with others. These guidelines are not intended to revise or supersede any existing “official” T-Trak information.

Guidelines for Straight Modules: All module construction techniques and materials are at the owner’s option. The track height of all modules will be 2-3/4" and easily adjustable to 4". The width of a single straight module will be 12-1/8”. The normal depth of a straight module will not exceed 14". Straight modules of extra width will be in multiples of the single module width after adjusting for track lengths.

Guidelines for Corner Modules: All module construction techniques and materials are at the owner’s option. The track height of all modules will be 2-3/4" and easily adjustable to 4", compatible with straight modules. Outside corner modules will be 14-3/8” square. Inside corner modules will be 18-1/4” square. The radius of the tracks will be 282 and 315 mm.

Guidelines for Junction Modules: Junction Modules provide the flexibility to assemble other modules in a variety of layout schemes and designs. All module construction techniques and materials are at the owner’s option. The track height of all modules will be 2-3/4" and easily adjustable to 4". The basic module will be 23-7/16” wide and 14-3/8” deep. The radius of the curved track will be 282 mm.

Guidelines for Special Purpose Modules: It is recognized that a special module, or set of modules, may be built for a specific purpose or to model a specific scene. These special purpose modules should be built according to the above guidelines and dimensions. No special module will interfere with efficient operation of the layout, either end to end or front to back. The owner of these modules understands that a particular layout may not accommodate their special purpose modules due to other situations or limitations.

Guidelines for Track: Two community tracks will be affixed to each module. The front track will be set back 1-1/2” from the front fascia; the second parallel track will be placed behind and spaced 33mm track center to track center. All tracks should extend evenly beyond the sides of the module. Kato Unitrack is the preferred track product for all of our T-Trak modules. At the very least, all the modules will have Kato Unitrack at both ends. The track shall be securely attached to the module base in such a way as to assure firm interlocking with adjoining modules while maintaining the geometry and efficient operations of the layout. Additional tracks may be placed on a module at the owner’s discretion as long as efficient operations on the community tracks are not compromised.

Guidelines for Wiring: Not every T-Trak module will have power feeds, but those modules that do shall be equipped with standard Kato Unitrack wires and connectors. The front community track will be wired with the blue wire to the front of the module. The rear community track will be wired with the blue wire to the rear of the module. In effect, this will yield a blue-white/white-blue configuration for the community tracks. The front community track will be identified as the “Blue Line”. The rear community track will be identified as the “White Line”. Other wiring for AC or DC accessories will be at the option and responsibility of the module owner. Any additional wiring shall not interfere with the efficient operations of the community tracks.

Guidelines for Scenery: Every effort should be made to show modules with scenery completed to the best of the ability of the owner. Modules under construction or without scenery will be accepted for showing only when needed to complete a layout that would otherwise exclude a completed module. Sky boards are at the option of the module owner and may be used as long as they do not interfere with efficient operations of the layout.

Conclusion: As much as we encourage and value innovation, the point is that each module should be able to effectively join with others in the layout. Each module owner bears the ultimate responsibility of insuring this is met, at the risk of not being able to join in the layout. All new modules should be constructed with these guidelines in mind. Every effort will be made to accommodate older modules produced before publication of these guidelines or under earlier versions of the “official” T-Trak information.
