I'm using Dispatcher to run trains automatically. ?Some of the track is
used for single line working so I've specified appropriate sections as
safe in the associated transits. ?Some of the safe sections coincide
with station platforms and so I've specified that the train pauses at
these section in the transit. I run the trains using 'to safe secs' as
the allocation method. ?Where the section comprises a single block the
train fails to stop. ?For sections with multiple blocks the train stops
as expected. When the train enters the section the speed is set to 25%
(33 in the loconet log). ?First entry is block occupancy detector
registering block/section entry, next loco speed setting, then the
previous block occupancy detector going low as the preceding block is
left. ?Detection is based on current sensing. ?The final entry is a
switch being set as result of the next sections being allocated.?

16:52:35.474: Sensor LS263 (3-P1) is High. ?(BDL16 # 17, DS7;
DS54/DS64/SE8c # 33, AuxD/A4/DS07).
16:52:35.542: Set speed of loco in slot 4 to 33.
16:52:40.900: Sensor LS293 (4-Up-A) is Low. ?(BDL16 # 19, DS5;
DS54/DS64 # 37, AuxC/A3).
16:52:40.925: Requesting Switch at LT106 (3-Dn -X) to Closed (Output
On).
?
The train then proceeds to the end of the transit at the current speed,
ignoring the transit section action to pause. ?When end of the transit
is reached and the train terminates the console log has the following
entry:

2018-06-21 16:54:08,410 dispatcher.AutoActiveTrain ? ? ? ? ? ?ERROR -
InterruptedException while watiting to stop for pause - {} [pause train
C170-19]
java.lang.InterruptedException: sleep interrupted

at
jmri.jmrit.dispatcher.AutoActiveTrain$PauseTrain.run(AutoActiveTrain.java:1506)
at java.lang.Thread.run(Thread.java:748)

I'm currently running version 4.11.7 but I think this problem predates
this version. ?It took a bit of time to clarify the circumstances.
?This is on a Mac running High Sierra.

Hi Steve,

If no pause is specified in the transit action then the train continues as
normal, but I have to deal with irate passengers.

Further investigation reveals that if I hold the next signal myself before
starting the train, then the train will stop showing paused in the dispatcher
status, and when the pause timer expires the status changes to waiting. ?When
I release the signal then the train restarts, which is what I'd expect.
?However having to hold and release the signal manually rather defeats the
objective of automated operation.

Hi Steve

On your test did you have 'All cars have resistance wheels' checked? ?I
normally run with this checked, but when I tried to think of potential
differences that could impact behaviour this seemed to be a candidate.
?Anyway if I uncheck this box the train pauses as expected. ?However it
seems reasonable to expect that I should be able to run with this box
checked if I have resistance wheels throughout, especially as having
resistance wheels is recommended for auto active trains.

Regards

Paul

I've just got around to a bit more investigation on this, mainly to see if I
could identify why it seems difficult to recreate the problem or identify some
other environmental issue. ?I've produced a greatly simplified layout panel on
the basis that if the problem disappeared then I could introduce features step
by step, however it's still there. ?To provide a quick recap, it occurs when

1) pause is specified on a section in a transit which comprises a single block
and which is marked as being safe in the transit?and,
2) on the Activate New Train panel 'all cars have resistance wheels' is
specified in conjunction with the Allocation Method being 'to Safe Sec'.

The train slows to 25% on section entry but its speed is not set to 0 and the
status in the dispatcher panel doesn't changed to paused. ?The train moves to
the end of the transit at the reduced speed and when it reaches the end it is
terminated as expected but a java exception occurs:

18:25:27.963 (138223) ERROR [pause train C170-19] AutoActiveTrain.java:1537 ?-
InterruptedException while waiting when paused
? ? java.lang.InterruptedException: sleep interrupted
? ?at java.lang.Thread.sleep(Native Method)
? ?at
jmri.jmrit.dispatcher.AutoActiveTrain$PauseTrain.run(AutoActiveTrain.java:1532)
? ?at java.lang.Thread.run(Thread.java:748)
?
I've uploaded the simplified panel, dispatcher options file and the train
description file in the hope that this will hope with spotting what's gone
wrong with my usage.

Thanks in advance
