There is a particular grade crossing on my layout that works normal when tested with just a single loco.
When the same crossing is tested with a longer Santa Fe Superchief passenger train with a pair of f7 units on either end of the train, the crossing acts goofy.
As soon as the train passes the gates go back up again. Good.
The bad. About 5-10 seconds later, the gates come down again for about 5-10 seconds then go back up again.
What's up with this?
I am using the 4-trigger, two way mode.
The train approaches the crossing then goes through a junction, diverging tracks following the crossing.
The final trigger the train runs over is beyond the switch points.
Still a single locomotive with no other train cars works normally.
Does having end helper engines on trains create special problems for ATLS?
Is ATLS sensitive to the makeup or size of a consist?
Should ATLS track triggers NOT have a switch in between them?
