Yes, I will need to dot the cantilever but not the bridge or the targets on the West end as I don’t model the main that far for lack of floor space.

Subject: Re: [CBQ] Signal Bridges at Burlington
If you are strictly being prototypical, you will need to include the cantilever at MP 204.99. This was installed in 1950 under AFE 45832. That AFE was for the CTC between Connett and Carthage
Jct. (in service in 1951), including all four 2 track bridges in Illinois, and they evidently decided to include the cantilever in Iowa as part of the AFE.
Since I model 1953, it looks like I won’t have to build bridges.

Attached is a PDF schematic of the cantilever signal at MP 204.99, plus a 3 track bridge of the same design as the 2 track bridge at MP 206.8. Although schematic in nature, they should help in
modeling signal bridges that are close in scale and detail.
I never found a detail of the truss diagonals attached to the horizontal beam of the cantilever at MP 204.99. I don't know the reason why they were added, but they are clearly depicted in all
photos I have seen.
I think the 2 track bridge at the west end of the Burlington CTC is a post-merger installation, but I can't prove it. It does not show up in any of the CB&Q signal bridge drawings or valuation
sheets, and it also does not show on any of the alignment charts from 1957 to 1970 (they all show ground-mount signals). Looking at the photo provided by Dave Lotz, it appears that the bridge has been spliced in the second panel from the right, and the design
is virtually identical to the 3 track bridge in the attached schematic. That schematic is of Bridge 15.02 at Gibson, Nebraska, a 3 track bridge that was taken down shortly after the BN merger. My guess is that the bridge at Burlington is the same bridge
after being shortened to 2 tracks. BUT again, I can't prove it.
Nelson,
Here is what was left of the signal bridge at the west end of the CTC through Burlington when they were installing the ATC signals. Unfortunately the searchlight signal heads had already been removed.
The photo was taken by Norman Schafer.

The photo of the interlocking levers and CTC panels prompts me to ask how they interacted, e.g. what did the CTC panel control and what did the levers control? Also, what date was the photo taken? My guess is that the interlocking was
for tracks West of MP 206.8 and the CTC panel was for Connett to MP 206.8.
Does anyone know of a photo of the signal bridge at the yard limit at MP 204.99?

Dave - Thanks for the clarification! - Louis

All,
Wood Tower was built in 1892, the telegraph equipment that was originally installed on the second floor of the Victorian depot was moved to the tower in 1931. The 1958 CB&Q annual report tells that CTC
was installed in 1958 along with 8 automatic grade crossing signals. The alignment charts agree with the 1958 date. Photographic evidence shows the CTC panel was initially installed in the tower, but the annual report also says that the CTC would allow for
the removal of Wood Tower. A Burlington Hawk-Eye article confirms the tower was razed in the late 1950s. Prior to the razing the CTC panel was relocated to the 2nd floor of the depot.
The CTC controlled operations from Connett, Illinois, (MP202.4) east of the Mississippi River, to MP206.8 immediately west of the Mt. Pleasant Street overpass. Am interesting note on the alignment chart for the Mississippi River bridge shows the CTC was installed
between signal bridge 204.33 east of the bridge to the signal bridge 204.99 at the Burlington yard limits as early as 1916!

Lenny - Did this board date back to the CB&Q era or was it manufactured and installed during the BN era? - Louis

Hi Lenny,
This is after they moved the board from the tower to the depot. Phil’s daughter, Paula, was in my high school class of 73.
Dave
Dave,
Thank you for the update. Above is when the machine was in service. Phil Woods is the operator. Several things have been blacked out such as the bridge locks and Ill. Jct.
