Jefferson Railroad Club

The Jefferson Railroad Club (JRC is the club, JRR is the railroad setup)

The Jefferson Railroad Club (JRC) is a model railroad club organized to develop and periodically operate the Jefferson Railroad (JRR) and the Jefferson Narrow Gauge Railroad (JNG). Organization at this time is informal (see membership requirements below) with all components of the Railroad itself being the property of individual members. Specifically, each member owns his or her modules and the common operating items such as the digital control system are the property of individual members as well.

Meetings consist of monthly organizational and work session meetings and quarterly operating sessions. During the organizational and work session meetings, members will plan for future operating sessions, work on individual or group projects, and discuss club matters. Operating sessions consist of assembling the Jefferson Railroad and operating it.

Currently all inquiries concerning the Jefferson Railroad Club should be directed to Bret Jones, either at Rail Tales (phone 434-984-1170) or by email (

Except as otherwise arranged, the Jefferson Railroad Club meets at Rail Tales on the last Saturday of every month at 5 pm. Specific scheduling can be found on the Rail Tales Schedule of Events calendar (


The Jefferson Railroad
The Jefferson Railroad is an HO scale module railroad. The mainline is HO gauge but local lines may be narrow gauge.

In keeping with Jefferson’s view of the nation during his day, the JRR operates according to a collective plan and requires that all components meet certain requirements but otherwise allows each member to introduce his or her preference in equipment and scenery. Some limitations on rolling stock size and type are necessary for practical reasons. Also, when operating in a public setting, a certain sensitivity to public taste is necessary (no controversial subject matter please). Otherwise, members are encouraged to explore individual interests. Currently, operating equipment represents time periods from the 1930s to the 1980s.


As currently constructed, the first set of modules covers a lot of real world distance. Our staging yard is considered to be Chicago and Tim’s module pair are referred to as the “Chicago Y” or Chicago as his modules access the staging yard. Facing the module, trains head East to the right and West to the left. As most railroads access Chicago directly or indirectly, this allows for most any roadname on the locomotives. Current operators with specific railroads are Burlington, The Otter Bay and Fox Island Railroad (a freelanced joint B&O/C&O bridge line known as the ‘Fox and Otter’) , and a CSX bridge line as yet unnamed.


Membership Requirements

Membership in the JRC requires the construction of one or more working modules to be made available for operating sessions, although the actual modules used at an operating session are subject to the needs of the operating configuration for that session as approved at a previous planning meeting. Modules must be made available for operating sessions if needed to fill out the planned configuration for that operating session.

Members may build modules in ‘sets’ or groups of modules that always work together. This is desirable for yards and other ‘operational’ components. Members may have sets of up to 3 straight modules or up to 2 straight and 1 corner module with the corner on one end of the straight(s). It is understood that during the planning for a session, a set will be incorporated and operated as a unit.

Members who wish to operate a locomotive during an operating session must bring to the session:

1) A DCC equipped locomotive

2) An NCE compatible operating cab or control device (Power Cab, Pro Cab, Cab4, or Cab 6)

3) Five (or more) pieces of approved rolling stock with cards for each piece of rolling stock.

4) Each card must have the name and a usable description for the car and a destination (module and industry).  The destination may be pick up (origin) or delivery.


Members contributing modules to an operating session must bring the following:

1) Any module or module set(s) agreed to during the planning meeting for that session including legs or other support structure(s).

2) Bus wire connectors to electrical join the power supplies of adjoining modules.

3) Quick clamps for connection of adjoining benchwork.

4) Six (6) line wire for connecting the control panels of adjoining modules or sets.



JRR Module requirements:

For discussion purposes, the assumption is that the modules will collectively form a rectangle and this rectangle will be operated from outside. Therefore, the mainline track will be closest to the ‘outside’ of this rectangle and the ‘near’ edge is the outside edge of the rectangle. Backdrops (if any) will be on the inside of the rectangle and therefore farthest from the mainline track. If turnouts or other features require control devices, those devices should be placed on the outside. Likewise, track interfaces should generally be on the outside.

Modules are to meet standard NMRA HO scale module criteria with specific exceptions and modifications.

1) You may use NMRA modules so long as they can be successfully clamped to JRR standard modules described below. Linear Modules must be 48” long and have independent legs that allow the module to be set up with the mainline track 40” above the floor. The width may be up to 24” although the typical JRR module is 18” wide to allow for easier transport.

Corner Modules are to be built with a nominal outside dimension of 48” square , although the corners may be cut off for convenience. The dimensions of the 24” wide modules are use for track spacing.

2) The Jefferson Railroad module design has Code 100 track resting on standard cork roadbed. The benchwork is 2” thick styrene insulation foam fixed to 1 x4 dimensional lumber (3/4” x 3 ½” actual size). The dimensional lumber provides a clamping surface at either end for standard quick clamps. Any module design which matches track and benchwork height and which allows for end clamping is allowed.

3) Track configuration for the mainline is NMRA standard double track Code 100 set 2” apart centerline to centerline. For 24” standard NMRA modules, the outside track is 5” from the near edge and the other track 7” from the near edge. For 18” modules, the spacing is 3” less (2” from the outside and 4” from the outside respectively). Mainline radii are to be no less than 33”. Mainline crossovers are to be a minimum of #5 (Peco medium radius). Maximum  grade is 1% on mainline.

4) All tracks which are not on the mainline are termed “Local Routes”. Local routes with outside connections should be spaced 14” from the centerline of the outside track (2” from the back edge of an 18” module, 5” from the back edge of a standard NMRA module. Local routes which connect to dedicated companion modules may have any spacing. Local routes have a minimum #4 turnout (Peco small radius), a maximum 4% grade, and a minimum 18” radius. Local routes may use Code 83 track.

5) All track and turnouts are to be laid so as to be DCC compatible or DCC friendly. All tracks are to be powered from a common DCC ‘bus line’ that has connections for adjoining modules. JRR standard wiring practice is for the track farthest from the outside edge to be wired ‘red’ and the nearest to be wired ‘black’. Modules which are wired differently should be marked at the connection points to avoid shorts.

6) Modules must have at least one (1) NCE compatible connection panel per module set, generally on the outside or operators side. The current JRR control system is an NCE Pro Cab radio system, so members may control their trains with a wireless radio device if they have one. Otherwise, they can plug into the panel nearest the train they are controlling.

7) Modules with destinations must have card pockets to hold the delivered cards for each car.


Operating Session Design: Sets and Blocks

Currently the JRR operates in the open space of Rail Tales workshop. As such, it can fit a total of five standard modules and 2 corner modules each side (28 feet) for a total of 4 corner modules and 10 regular modules. For planning purposes, the configuration that fits into Rail Tales will be referred to as a Block.

The Jefferson Railroad will be designed and built as a series of Sets which then make up a series of Blocks. Each Set serves a role on the railroad and the Block serves as the basis of an operating session. Each operating session at Rail Tales would use one Block.

Blocks will be designed with connections that go outside the Block so as to facilitate connecting with other Blocks. The goal is for the Jefferson Railroad Club to set up once a year at a location that can accommodate multiple Blocks.

The current configuration allows for 4 members to have 3 module sets or for more members to contribute smaller sets.

During an operating design session, the club will determine the configuration of modules to be brought by members to fit the space. The club should also plan jobs and contributions of rolling stock from each member to allow all members to operate in the given space.

Ideally, each Block would have at least 2 and preferably 3-4 yard areas. Each yard would have a switcher position to work the yard. At least 2 and possibly as many as 4 other operators will be able to work the mainline. With a larger number of operators on the main line, a dispatcher may be necessary. Also, as most turnouts will be manual, operators can take turns assisting with turnouts and coupling/uncoupling of cars. Each block can therefore accommodate 1 operator per yard, 2-4 mainline operators, a dispatcher, and several assistants handling the rolling stock.



For simplicity, all cars and trains begin and end each session in Chicago. Cars are randomly assigned to each locomotive (operator) and delivered to the destination on the card for each piece of rolling stock. Destinations within yards are dropped at the yard entrance and delivered to the final destination by a yard engine. Destinations at simple sidings are set out by the road engine. Once a train has delivered all its cars and cards, the operator draws five cards from delivered pockets and has to collect those pieces of rolling stock and take them to Chicago. Cars in yards are assembled by the yard engine. Those at simple sidings are picked up by the road engine. Once all cars are back in Chicago, the session ends.


The Jefferson Narrow Gauge Railroad

The modules for the JNG are 48″ long and 18″ deep nominal and are designed to fit flush on tables. The minimum radius is 18 inches and the turnouts are standard #6. The module design uses a single mainline set 6″ from the front. The construction of the layout is the same as for the HO.

The module set design uses a fixed rigid alignment template for pins and track placement, which is available from the club.
