An Overview of my Joint Line Layout

Layout Plan


Layout Type & Design Specs


  • HO scale, walk-in point-to-point around the walls single-deck shelf with open staging; no continuous run or helix
  • Represents a single Station and environs rather than traditional running between multiple Stations
  • CTC controlled single-track mainline with ABS intermediate signals
  • NCE DCC control, maybe some sound
  • Minimum mainline radius 42” or greater with spiral easements; min industrial 24” or greater
  • Maximum grade 1%
  • Mainline route & passing siding turnouts #8; all others #6 or #3 wye
  • Track is Right-O-Way, Micro Engineering and Peco code 81/83 flextrack for mainline & passing sidings and staging yards, code 70 other tracks
  • Roadbed is commercial HO and N scale and sheet cork
  • Maximum train length is around 24 feet, or 3 6-axel locos, 25 cars, caboose
  • Deck height is 49” at lower (south) staging yard, 54” at upper (north) staging yard; ~50” at Springs Yard
  • Benchwork is 3/4” plywood subroadbed on 3/4” plywood brackets secured to the wall or pine L-girder, joists and risers

 
Operating Crew Positions
  • Dispatcher/Agent/Yardmaster/Clerk ~ 1-2 people
  • AT&SF Local Engineer & Conductor ~ 1-2 people
  • D&RGW Local Engineer & Conductor ~ 1-2 people
  • CRI&P Local Engineer & Conductor ~ 1-2 people
  • USAX Local Engineer & Conductor ~ 1 person
  • AT&SF, D&RGW, C&S-BN road Engineers & Conductors ~ 1-2 person crews as needed

 
Operating Scheme

The layout depicts the Joint Line as it runs through an extended rendition of Colorado Springs. This single station focus is an approach common in the UK but gaining popularity here in North America, although seldom on a layout of this size. Focus will be on the local jobs operating out of and into the D&RGW Springs Yard rather than on mainline trains running over the length of the railroad.

AT&SF and D&RGW through trains on the mainline will set out & pick-up cars to feed that local operation, and provide interference with the local jobs working along the mainline, along with BN freights and unit coal trains, making things interesting for the local crews.

There are four local jobs: AT&SF and D&RGW each keep a switch engine & caboose in the Springs to serve their respective customers, while CRI&P ran a daily turn from Limon, CO west to the Springs and return. All three roads use the Rio Grande Springs yard, although there is also a vestige of Santa Fe's original yard. In addition, the U.S. Army's Fort Carson railroad switch engine handles interchange with the Joint Line railroads.

Besides customers adjacent to the D&RGW and AT&SF yards, there are four distinct switching districts served by these local jobs: Kelker to the south (shared AT&SF-D&RGW-US Army), Roswell to the north (CRI&P), Russina further north (D&RGW), and Pikeview to the east (not drawn, shared CRI&P-AT&SF).
