The point limit marker
Placing and assembly
One
of the risks involved with points and signals is the so-called flanking
accidents, where to engines approach the same point and stop too late.
This often results in incidents where both units are rendered
temporarily hors de
combat. In the worst case, where one of the involved trains is
substantially heavier than the other, the outcome is more dramatic - the
lighter unit is flipped on its side.

To avoid
this a simple signalling deviced is employed. |
The German railways use the so-called
Grenzzeichen (point limit marker)- DRG K12, DB Ra12, DR So 12
respectively - which is made up of a pole with a red and white
checkerboard cap.
The marker is placed next to the straight part of the point in such a
way that a line from the center of the straight track, through the
marker, to the center of the branching track is a minimum of 3.5 meters.
This allows trains that fit inside the standard loading gague to pass
clear of eachother.Obviously this takes
keen eyesight on the behalf of the engineer, but he will usually be
assisted by a "Rangierer" that guides him with hand signals.
To ensure as correct a placement as possible in
Trainz I have devised a little tool to facilitate placing the marker. |
 
Point marker and placement tool
|
| Place the tool on
the straight leg and lip it to the inside (if necessary). Them move it
towards the frog until the perimeter touches an imaginary center line on
the branching track.

|
Place the tool on the straight leg and
lip it to the inside (if necessary) and move it into the center of the tool.
When in place, delete the tool by clicking its perimeter with the delete tool.
And that is all there is too it.
  
Note! If it wont move or flip, save
your work and exit, then re-enter your project and you will find
the motor has been unlocked. This is apparently something that relates to build
404 and hopefully it will be fixed in the future.
It is not a fatal error, but it tends to get a bit tedious.

Some philosophy:
One might ask to what need are
such details? My answer is- they add realism to the game. With UTC you
have the ability to apply out of cab views, the prime exponents for that
are the little Burlington shunter used in the Blue Sky Steel scenario,
where you are able to ride the coupler and the DB V218 with its
head-out-of window views. In the same style you can create
riding-the-footstep view on a DB V60 or a DSB MH shunter, and suddenly
the marker is an integral part of your everyday as a shunter. You also
have the possibility of turning the marker into a non-functional point -
like JoshEH's skycam - which enable you to use the point-view (F2) and
play the part of the "Rangierer" and depending on the tolerance of your
family, friends or neighbours use a whistle or arm/hand signals to
direct the shunter towards the marker.
