The official and updated Missouri Statewide map

[railroader3921]

Just did a bit of digging around, and I have made a VERY interesting discovery.

According to a post on this thread, there are two undocumented STH-10's that are (as of that post in 2018) active in St. Louis County. They are located at 38°41'8.89"N 90°31'25.59"W , and 38°40'46.10"N 90°32'41.51"W . They are owned by the water treatment plant, and go off alongside the county's Whelen's.

West Plains is still missing a ton of E-Classes according to the USA siren map owner, if you have info or locations about these post them here.

Map and it's borders are cleaned up slightly along with more location updates.

I think this might be a siren not yet marked, could possibly be a Whelen, not on streetview at the moment.

We hit 5,000 views on the map!
Foreign sirens also have diamond shaped icons now, thanks to Independence county, Arkansas for that one.

Important News, two Cyclone 120s left in the state, only one active as of now. Eldon's cyclone has most likely had the plug pulled leaving Carrollton as the only active cyclone.

There is an abandoned 5T out in the old Berkley, MO neighborhoods by the airport.

38.74796366287104, -90.34136845464057

If you're driving by on 170 or Airport road and look at the right time, you can see it.

Here's a few more:

St. Louis City STL-10s

1: 38.630442369903754, -90.22491903709737
2: 38.614446709288494, -90.26446761056097
3: 38.67228674184824, -90.27867452345099

The 2001-130 that you have out by Lake Quivira in Overland Park is actually a Model 2:

39.03036742276896, -94.77043960295542

Additionally the Model 2 that was in Smithville, MO was actually a 5.

The ACA Screamer in Summerfield, IL is a S-5.

With all of that, this is a great map! I had no idea that Kansas City, KS had an abandoned Thunderbolt!

Uhh, you marked Eldon's RM-127 as inactive. It isn't, and it can be heard in my video. Skip to 3:18 in my video (https://youtu.be/FNINn5XUmnw), and you'll hear it. It just activates/deactivates a few seconds after the whelen's, because it probably uses different tones.
