<h1>JMRI: BN-1989 Signaling Definition</h1>
|
|
This directory contains signaling definitions corresponding to the BN (Burlington Northern)
|
|
rules as described in the October 1989 Burlington Northern Railroad Southern Region, Nebraska
|
|
Division Timetable #2. In effect at 0001 Continental Mountain Time, Sunday October 29, 1989.
|
|
<p>Per Burlington Northern General Signal Instructions, Dwarf signals display the same
|
|
aspects and indications as high signals.</p>
|
|
|
|
<p>Signal aspects can be referenced in the 1991 timetable here:-</p>

|
1991</a>. Note that the double head searchlight with Lunar is the only mast able to display
|
|
all of the aspects. Not all of the possible masts have been defined but there is a varied
|
|
selection here that should cover most requirements. Due to the nature of this being a
|
|
simplified prototype system it is not easy to display all the possible variations of the same
|
|
aspect on a mast and this should not be necessary. Where a mast can display different
|
|
variations of an aspect (e.g. Diverging Clear) where possible the Restricted Proceed aspect
|
|
is shown for the alternative diverging route.</p>
