Today’s Top 5

Snake Eyes

I'm thinking of some fellow holding up a convenience store; the clerk pulls out a double barreled shotgun, and this is what the robber sees.

Lobster, lettuce

and everything in between.

Tunnel locomotives

It would be nice to have a large format photo of one of the period engines on Shorpy. Most of the ones I've found are kinda fuzzy and don't do justice to the picture of the tunnel.

Street Lamp

I want this street lamp in my driveway! I have scoured the internet in search of appealing exterior lighting, and haven't found anything nearly as interesting as this one. I don't know what it is about it, it's just perfect.

Under-Running Third Rail

This is the "Under-Running" type of third rail, where the pickup shoes on the locomotive run on the bottom of the rail. The rail is sort of hanging from C-shaped insulated supports. The insulators are under tension.

This is superior to the common "Over-Running" third rail because the top and both sides of the electrified rail can be protected against accidental contact. In this photo, one can see that the top and both sides of the rail are covered in wooden sheathing. (In the more common Over-Running 3rd rail, only the back side and the top of the rail can be guarded; the track side must remain exposed.)

This is the type of 3rd rail used in other New York Central System electrification projects under the control of VP of Engineering William J. Wilgus. This type of 3rd rail is used in Grand Central Terminal and on all line approaching it. (The former New Haven transitions to overhead wire, but operated within NY City limits on the 3rd rail.)

All of this sort of third rail in the NYC /Westchester area has been changed from wooden sheathing to fiberglass sheathing, which is safer because it cannot absorb water.

Now, if Shorpy could only find a photo of the electric locomotives which traversed this tunnel.

Do not touch?

That sign is an understatement. I believe those rails carried 750 volts DC.
