No railroad allowed switches on bridges, did they?

[OldEastRR]

My junction dilemma can be solved if I put one of the turnouts on the bridge. Alternately I would have to extend the embankment and shorten the bridge to get the track arrangement. Or I can  do what I want, right?

This was done with the switch points on one end and gantlet track across it:

Umm, that's not a switch, but a gauntlet track.

PRR's famous "wye bridge" over the Allegheny river at Oil City had the point of the wye right in the middle of the river.

While the north leg track is removed, simply Google Earth Oil City PA and look in the river, you can't miss that crazy bridge.

Someplace I've got shots of crossover switches on the two tracks.

It should also be noticed that Rockville has switches on it today - two by my count.

I'm sure there's more.   Typical?   Never.   Impossible?  No.

Seems to me Keddie wye just missed:  http://forum.atlasrr.com/forum/data/BN4EVR/20051113223352_IMG_1020.JPG

Rockville still has an entire interlocking on it. CP Mary.

Also, there's one right up the river a little bit too: CP Cannon over Sherman's Creek.

Jerry Britton even built a working model of that. I think someone still has it (@dougnelson maybe?).

Speaking of switches on bridges, I have a similar question. How common are passing sidings on bridges?


Hmm... what a dumb
question...

Bethlehem, PA had one.  Former Reading bridge for the Saucon Hill.  The switch was actually a later addition to allow a connection to the Lehigh Valley.  The switch and track the GP8's are on was removed, but the track to the right remains a very active part on NS.

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

The bridge leads to the Oregon Trunk which also has this awesome bridge.

One of CSX's [nee B&O] bridges over the Potomac River @ Harper's Ferry has a switch right in the middle of it too.


And the Lehigh Valley had a bridge over the Lehigh River in Bethlehem PA with a switch on the deck girder portion, right next to the Hill to Hill traffic bridge.

So how many example you want?  I could add several more.  Turnouts on bridges don't even fall into the uncommon category.  If you need to do it, do it.

In my particular case, the CGW opted to not have the switch points on the bridge, so they made it a longer turnout where the points and switch stand were off one end.

I am aware, this one did have switch points thiugh at one end. I know it is not a full switch but just one way they were set up.

funny, but I did what amounts to half an interlocking on a bridge and got my  handed to me on a platter about how unprototypical its was . . . .

Because you tried to do it on an open-deck pile trestle.  Location, location, location!

Not quite a traditional passing siding, but the Victoria bridge in Montreal has a double track main and a double track detour so that if ships are crossing one of the lift bridges, trains can still get through the other span.

Because it is man...un-prototypical that is.
Doesn't make you a bad person though.
