No railroad allowed switches on bridges, did they?

[jagged ben]

In the great state of Washington, near Wishram on the old SP&S.

Yeah, but they're so scared of the train derailing on the switch that they have crews lined up in high-rail vehicles to help out in case of disaster!   

(Just kidding.  Nice link.)

Roads going through turnouts aren't that uncommon, although, as others have said, avoid the moving parts. 

As for Wishram, I don't remember ever hearing of a derailment on that bridge.

If you want a wye on a bridge, look at BNSF's Latah Creek Bridge in Spokane.  Trivia:  There is no "Latah Creek" under it, the water is officially named Hangman Creek.  Latah was the original native name, and the locals have been trying to get the name changed back for years.

Here's a better photo of what I was planning.

Not ideal, but the best I can do with the space.

I have a bunch of turnouts in the roads on my layout:

Not really a tower controlled interlocking though.

Yeah, that's a good point. I wonder how Pennsy would've run the control rods through the streets.

You know what? I'm not gonna worry about that...

Your pavement doesn't even go over the frogs - you got no problem there.

This has been a pretty good topic -- hopefully it will be helpful to others with road/bridge/trackplan problems.
For intense switchwork/highway intersection situations, the RR and city combine to put a short but scary-sloped overpass over the track. In Ed's case all he needs do is put half of one in, the other half can be off the layout. Also, the steep low-height underpass works.

[nkalanaga]

No problem with that at all, and it will even eliminate the need for replacing the ties.  If those are feeders in the crossover track, use a removable crossing (wood or rubber, depending on your era) and they would be accessible without damaging the scenery.

Ed,

I have a road thru a couple of switches...it's a siding off a branch track tho, not a crossover

[rschaffter]

If I'm reading this right, in Penn Central days there were five on the PRR's Rockville Bridge over the Susquehanna River...

...And with a different track arrangement these days, still five...

This is an old NP mainline that ran through town in the alleys. Abandoned now (obviously) but there was a switch right in the middle of this alley that ran to a short spur. The entire switch was embedded in pavement:



Notice the steel channels that left only enough room to get a wheel tread through.

Streetcar-like switch plate in the pavement:



The switchpoints were fairly short; the arrows note where the rail ends -- not far from the outer rails.

NP?  If that's the Northern Pacific, where is it?

If it isn't the Northern Pacific, what road is it?

[wazzou]

Yeah, I'm not buying Northern Pacific "mainline".

[nkalanaga]

I'll easily accept a branch line somewhere, but no, not THE "Main Street of the Northwest".

Narragansett Pier, maybe?

[OldEastRR]

Well, a "main" route of a branch that ran through the city and on the other side connected to a GN main. This track was the thru route that linked an NP line to that GN line, and since it got to town last of 3 railroads the only route through was a long series of alleys. But yes it's former NP.
Anyway, just wanted to show the embedded turnout on a regular (not streetcar) line.

[nkalanaga]

OK, it is Northern Pacific, but what town?  It almost has to be the Midwest, because there aren't many towns west of Minnesota where the NP was the last to arrive, unless they're the only railroad.
