Can you give me some views on the right number off blocks in a storage yard.?
I intend to store 2 trains in line in each fiddle/storage yard. So my thinking was three blocks. One near the end about the length of a long loco. Say last 10%. That will detect the first loco and stop near the exit when using dispatcher.?
the second block being about 40% into the storage line. This would detect a following train and stop it after crossing the boundary.?
With the remaining entry block covering the first 40% would act to slow the loco. ?Prior to crossing the next block.?
on the other hand do I need four blocks.?
Such as 40%,10%,40% and last 10% or is this a waste?

I have storage lines that store two trains too - although the assumption is that they will each store one long train and one short train, as they're not long enough for two long ones.

?

I did it with three sensors -

1 - the front of the storage line, don't cross this one

2 - just after the length of my longest short train - short trains will not cover this sensor so long trains can pull up behind. Long trains will cover this sensor so short trains won't be able to pull up and cover it

3 - just after the length of my longest long train - meaning short trains can pull up behind

?

I used IR sensors for this as they're more straightforward and the intention is to determine static positioning, not motion.

I have 3 total.

The yard entrance splits and each has a detection block.

?

One is the freight arrival and Dispatcher brings train to a stop 80% into Block #1.?

Yardmaster takes over to break up the train.

?

The other is both freight departure and bypass to the passenger terminal.

Dispatcher brings passenger train through yard departure/bypass and Block #2.

Passenger terminal is Block #3 and Dispatcher stops train within 90% of the block at the terminal.

?

The yard tracks are not detected.
