SAND ON RAILS and SIGNAL PROBLEMS

[Jim Holland]

Greetings!

	You didn't miss the original message  --  it wasn't posted here!

	And the IT messages were on another list as well, not here.

	The subject of electrical conductivity with models came up on a list
which discusses models and I relayed information that showed that the
prototype had conductivity problems as well!

	I thus mentioned PRCo and the prohibition on sanding on the interurbans
unless an emergency.  Also saw an accident with lrvs in SF where track
circuits are used to set turnouts.  An operator sanded the rails and set
the turnout correctly but the sand broke the contact and a following
truck threw the turnout which caused the rear end of that train to smash
into the one beside it and derail.

	Some of the PRCo 1700-series interurbans had a switch on the dash to
set the trackbrake so it would scrape along the rail and clear it of
sand!
