HWD CRASH  problemm - How to insulate TurnOut?

 

 

 

DESIGNATION:

 

May be, this topic can be  more actual for people who driving whole layout by using dispatcher panel, or also for fully authomated layouts

 

EXPLANATION:

It is well known fact that Turnouts of almost all manufacturers have small length of adjacent way,

so that, if we insulate turnout itself from adjacent block section with train, other mooving train, passing through turnout, can mechanically hurt this train  even it's resistor's wheels belong to separate insulated block and occupancy detector will report that turnout is free and as a result - incoming green light... but crash!!!

 

QUESTIONS:

 

1)

As i believe, for right operation of whole layout and program  we must solder to both  turnout's adjacent ways short parts of track, and just after that we attach insulated block section through insulated rail joiner.  The length of this short parts of rail must be choosen so that both trains, belongin to adjaceent insulated block sections cannot mechanically prevent for mooving other trains.  It's a HWD dimension rule!

 

Is it Right?

 

2) All turnout must electrically  belong to incoming and outtgoing ways of station ,but  station ways must be fully insulated from both ends, taking into account upper described HWD dimension rule .

 

3) All length of  each insulated block section on station ways  or adjasent ways (with Turnout's length) must be longer than the longest train. (in aim for correct operation of authomatic braking )

 

Is this formulations  Right?

If you're working with blocks, it's generally recommended to leave turnouts out  of the blocks. The minimum length of a block is also at least as long as the longest train plus a little bit for decent deceleration etc.
