oNeTRAK layout at Adliswil 2000 Convention

MODULES/LAYOUT SAMPLES

15

This is the track plan of the Dease Lake &
Northern,  which  proved  to  be  a  real  show
stopper during the 2000 Adliswil Convention.
While  all  elements  follow  oNeTRAK
specifications,  they  were  designed  to  suit
this  configuration  and  the  landscape  flows
smoothly from one module to the next. Such
a  layout  is  not  expected  to  see  fast  trains
looping.  The  main  attraction  is  the  barge
operation  over  a  lake  made  of  real  water.
Operations  follow  time  table  and  waybill
instructions.  Several  industries  are  served
and cars are swapped with another railroad
symbolized by the tracks on the interchange
at the left side of the layout.

DEFINITION

oNeTRAK is an NTRAK compatible
single-track  branch  line  that  can
augment NTRAK layouts.

MAIN GOALS

1.

Lightweight,  simple  to  build

modules, especially for beginners or
those with limited transport capability.

2.

Provide  an  alternative  to  three

track modules that can be connected
to  an  NTRAK  layout.  Connected
layouts encourage team building and
enhance fun!

3.

Easy home layout integration

4.

Extend  the  NTRAK  Red  Line

Route at shows

5.

Provide a branch line for more

prototypical operations.

6.

Provide  an  easy  way  to  model

scenes with single track and tighter
curves.

7.

Provides a section of the layout

for  serious  switching  operations
when the rest of the layout is running
lots of trains to hold the attention of
spectators.

INTEGRATION

oNeTRAK modules can be used to
build  stand  alone  layouts  with
emphasis  on  operation  or  can  be
connected  with  an  NTRAK  layout
using  junction  modules  either  to
lengthen  the  “Red  Line  Route”  as
seen on the sketch below or to have
a branch line with sparse traffic. As
the module design should permit both
uses,  all  relevant  standards  for  a
conventional  NTRAK  module  must
be met by any oNeTRAK module.

ELECTRICAL ISSUES

NTRAK  layouts  in  general  and
oNeTRAK modules in particular may
be  operated  using  conventional
analog  technology  or  digital  DCC
equipment. A module should conform
to both requirements even if its builder
or owner only intends to use it in one
of the two modes.
