Good Morning!

	Addition(s) from #33 on listed below; numbering of
locations might expand or contract depending on what signal
sections could/should be grouped together:::::::

01.)--42-Dormont had standard US&S 3-light signals on
	prw from Dawn to Beechview.
02.)--Palm Garden Trestle had dual light dwarfs in latter
	days but not when first built.
03.)--Elaborate interlocking at Dawn Jct with double contact
	for turnout.
04.)--38-Mt.Lebanon Dinky track to Castle Shannon
05.)--23-Sewickley had signals on single track on
	Neville Island as well as west of Coraopolis.
06.)--24-Schoenville had working signals before it was
	isolated.
07.)--27-28-30--lines prw from West End to Idlewild Rd.
08.)--39--Brookline on single track prw to loop.
09.)--40-Mt.Washington on 3-different sections.
10.)--49-Beltzhoover on Arlington and Climax/Gearing Streets.
11.)--55-line at flood-gate single track in E.Pgh.
12.)--56-line prw thru Buttermilk Hollow; don't know about
	side of road prw along Mifflin.
13.)--58-Greenfield along, uh, Greenfield.
14.)--67-line along non-clearance turns at Rankin(?)
	Hastings(?)
15.)--68-line in Duquesne on single-track.
16.)--Trafford at one time before single franchise car.
17.)--94-line in Aspinwall.
18.)--98-(99)--Glassport (Evans)
19.)--Elaborate intersection at Itin/Spring Garden
20.)--4-Troy Hill single track and siding.
21.)--3-Millvale single track to loop at end of line.
22.)--5-Spring Garden single track and passing siding.
23.)--Elaborate intersection at Brighton/California.
24.)--6-Brighton Cambrone to Wynhurst
25.)--8-10--lines from Perrysville to Keating(?)
26.)--Signal to show activation of RR-style flashing
	grade crossing lights for crossing Perrysville
	at Keating.
27.)--10-West View at 3-X-Overs; what about other prw here(?)
28.)--65-Lincoln Place single track and sidings as well as
	Junction with 56-line.
29.)--W1-Jefferson-Maiden
30.)--W4-East & West Washington
31.)--W5-North Washington
32.)--SOUTH---HILLS---Jct  --  Tunnel Interlocking and
	Derails.   Interlocking and turnout Display with
	double overhead contactors to set turnout outbound.
		Amazingly complex intersection with 3-main
	throats	leading to//from Tunnel:::::::
		A.)--Interurbans Charleroi, Washington
			Castle Shannon
		B.)--38,39,40,42
		C.)--44,48
		Considering the Admin loop and yard leads
	for all	these lines and that the  ONLY  signalling
	in this	area is mentioned above  AND  considering
	the number of cars that have to make the loop
	to/from the yard and their respective lines WithOUT
	additional signalling is quite extraordinary.
	If ({[pat]}) signalling is anything like SF Muni
	subway, PRCo was able to move infinitely more
	People/Hour thru the Jct. than  ({[pat]})  with
	only 3-lines - Dormont to South Hills Village,
	Drake on Overbrook, and 49-line	hourly(?)
33.)--Dwarf Signals thru South Hills Yard for 38,39,42.
34.)--Interlock and Derail from Tunnel Yard outbound at
	Palm Garden to main line of 38,39,42.
35.)--Possible interlock southbound into Palm Garden Loop
	And northbound from Palm Garden Loop to 38,39,42
	mainline.
36.)--Possible interlock northbound from east-side yard-
	throat, Tunnel yard.
37.)--Others????........

Waiting for a bus is about as thrilling as fishing,
	with the similar tantalisation that something,
