Welcome to the

 

Great Northwestern Railway

 

A freelanced HO scale switching layout.

 

 

SW-1500The story of the GNW is that they bought up the old narrow gauge right of way from the Colorado Southern (itself later merged into the Burlington Route and the AT&SF), including the old R.O.W of the Denver, South Park and Pacific, which the GNW has rebuilt in standard gauge.  Later acquisitions developed the GNW as a north/south line connecting the Great Basin to south central US.  It is now primarily a bridge line between the SP at Tucumcari, NM and the D&RGW at Green River, UT.  There is also the South Park Division providing connections to Denver, CO. 

 

The model RR is set somewhere between Colorado and New Mexico along the main.  Only a few dozen feet of mainline are modeled, connecting two 8-track staging yards.  A single major yard, Valley Gate, is placed along this main.  A branch line comes off the main to Warm Springs, a fairly industrialized town.  The operating scheme is the exchange of cars between industry and mainline trains by means of locals and manifest freights.  There is also commute service between Valley Gate and Warm Springs, and a daily Amtrak train, the San Juan, through Valley Gate.

 

The era is late 70’s/early 80’s with a mix of first and second generation diesels.  Due to limited cashflow, the GNW necessarily uses second hand power for most of its trains.  SP provides the power for most of the through trains.

NEWS FLASH: TRAIN SERVICE STARTS TO
BLACK WATER FALLS RESORT AND HOTEL

 

Size:  The layout is situated in a area approximately 15 x22, configured with an around-the-walls shelf and a single peninsula.  With 28” min radius curves, there are a couple pinch points with less than 2’ aisle width.  

 

Train Controls:  Train controls are DCC by MRC PA Wireless and PA tethered throttles at the yards.  All locos are sound equipped. 

 

Train movement scheme:  All trains except passenger and one express freight are extras and run off a train sequence.  Passenger service is run per the timetable.

 

Authority to the main is via written track warrants, as issued by the dispatcher.  Operators are expected to know the limit of their authority at all times.

 

Car Movement Scheme: Cars are moved by car cards and waybills.  The Micro-Mark card system is used.  “Train Packs” are used to define trains and carry instructions.
