This evening as a couple of trouble making friends pointed out to me I

have a situation which does not appear to be prototypical

I have a situation where a spur is located inside the os section.

It lookes like the sketch below. This situation has only been in

place for over 20 years and NOW they point this out to me.

/ /

o /

/

(passing track) /

---------------

(Main Track --o / Pulp wood loading

---------------

--o

They suggested that since the area is rural, no self-respecting

railroad singal department would allow an industrial spur within the

limits of the OS.

Does any one care to comment?

Richard,

most of them have left for the evening, but one of them is still here and he says that he is trying to get me to improve it. I wouldn't be having this trouble if I hadn't gotten into DCC.

Hopefully it looks better than the picture. "ASCII" art never turns out the

way you draw it. Can't make heads or tails out of the diagram.

If you looked you could probably find dozens of examples.

Is it a CTC control point or is it in a manual interlocking?

If its in a CTC control point they will have to take the switch in hand

throw, make their moves in hand operation and restore it to power when they

are done.

I agree with Dick Foster: it's your railroad and there IS a prototype

for everything. Just put in a dwarf to protect against movements out of

the spur and you'll be just fine!

The signal protecting movements across that switch should have a

restricting indication for movements into the spur, same coming out of

it... That is pretty easily done by having some contacts on the throw of

the switch set up a condition where an alignment into the spur will kick

the signal into a restricting aspect...

Another option would be to keep the switch as a power switch and have to

request the dispatchers permission for track-and-time and to take the

switches at the OS on hand for local switching.

Explain to them that there was an elevator on the passing track at one time,

now since long ago shut down and torn down... The railroad just converted it

to a passing track since they now own the track and the main line was never

changed. The signals were placed there after the railroad started to use the

old elevator track as a passing siding in order to met the signal rules

required at the time...

You might need to add some broken fountain brick stuff and old road bed

although covered by lots of weeds:-)

I would say such an arrangement would be rare in rural areas, but not

at all unusual in an industrial zone. You don't say what era you are

modeling, today there would have to be a signal controlling movements

out of the spur and back into the OS, though it might only display

Stop and Restricting. But I've seen several locations back in the

1950s and 60s where the only protection on the spur was an electric

lock on the switch. As for justifying the spur location in a rural

setting, put in a creek or a road or maybe even a cemetery; anything

to get in the way and give a reason for locating the switch where you did.

I will repost the track diagram as a pdf.
