Anyone model this?

I tried to sell my two cents worth, but no one would give me a plug nickel for it.
I don't have a leg to stand on.
Odd that it continues on past the frog to the left. My impression is that these usually relocate the points to a better location, but once past the frog is just the standard two rails.

It's based on a sketch in the book Freight Termimals and Trains by John A. Droege. In the sketch it appears that the gauntlet (4-rails) starts about 1 car length left of the switch.
I would think that there would need to be a reason for something like that to be built. Otherwise the simplest method would be used.
Wouldn't that be for room to grow or room to move cars around if needed? But convenience sounds a lot better. Since we are not actually at the site there could be a reason we are not thinking of.

Reason:
A facing point switch is required to serve the industry. The main line is double track with trains operated in the direction shown by the arrows. Because of safety concerns, the railroad does not allow facing pount switches to spurs on the main line.

There is still a facing point.

True, but the facing point is on the Gauntlet, not on the main line. The Gauntlet is connected to the main on the left by trailing points. No connection on the right.
No, the right end does not have a set of points. There are only 2 sets of points, 1 for the gaunlet at the left end and 1 for the turnout itself. There are 2 frogs as well.
The sketch in Droege's book (referenced above) page 44 provides a clearer drawing.
Interesting, I haven't heard of one of these before. I wonder if any were ever built.
Enjoy

DSchmittBecause of safety concerns, the railroad does not allow facing point switches to spurs on the main line.
Ahhh. So I guess they're afraid that mainline trains might pick the points, so they resort to a trailing-point switch and the gantlet/switchback. The book by Droege dates to 1912. I wonder if he based this on an actual prototype.

The drawing is on page 57 of the PDF file (page 42 of the book.) No mention of a prototype example, just a hypothetical situation.

Okay, I enlarged the picture and see what you mean. So a switchback is created.
No thanks. I hate those things. Plus now you'll need a run around somewhere to get the pickup behind the engine

FYI it's the first edition.
A second editon dated 1925 was reprinted by the NMRA. The part about this gauntlet is pretty much the same.

Or you place it between cross overs to/from the other main line so the way freight can cross over, run wrong direction on the main and use it as a trailing point pickup/drop off, and cross back to opposite main line. Looks like a good project for NMRA achievement program.
Google Gauntlet track, and you'll see many examples. There was a dissussion on this a couple years ago in here. The way I see it, there is a point on each end, to control access to the gauntlet, and the frog is actually on the gauntlet track, allowing the main line train to run through without actually passing over switch with a frog.

Mike,
There are only points on the left hand side and on the guantlet itself. Click on the photo and go to full size. The reason is to elimiate facing point turnouts on the main line (I read the book referenced) because of concern about high speed trains picking the points. And you still have to have a frog on the main line no matter what (look carefully there are actually 2 frogs).
OK, I see it.
mbinsewi OK, I see it. Mike.

Here it is. The gauntlet is right in the middle of the mainline.
Rich,
The mainline is the black tracks, the Gauntlet and spur are the red tracks.

It would simply not work.
Still a facing point turnout, but now, once you have pulled the car with the locomotive, you now have a locomotive trapped behind the car, with zero run-around, and zero chance of having a double tracked main line tied up with a local running against traffic, or having a restricted speed train with a car first move, holding up traffic on a clearly busy corridor, as it was double tracked, and traffic blocked for one way mains, because this facing point turnout is now on a gauntlet track, trapping the locomotive.
You would need either a trailing point turnout, or a crossover to allow a trailing point move from the other main.
Either option rules out this gauntlet track. It simply would not work, nor would ever be used in real life as depicted.
And the never work is why it will never be on my layout.

OK, I had to take a few more looks, and what I missed, is the there are no points to access the gauntlet track on the right hand side of the switch, only on the left does the gauntlet track rejoin the main with points, so a train moving in the direction of the arrow, would have no points to cross, just the second frog.
So to access the gauntlet spur, the loco would have to shove past the gauntlet spur, than access the gauntlet via the points on the left, and pull back on the gauntlet track to the spur switch.
Actually it would work. Railroads do have crossovers between double track mains. and also sidings on double track mains. The only difference between this arangement and a spur accessed by a switchback is that here the tail of the switchback is a Gauntlet. I do not know if the Gauntlet arangement was ever used, but the switchback arangement (although not ideal) certainly is and was where necessary to serve a valued customer.
This example is from the early 1900's when double track lines had a designated direction for each track and if signalized, were signaled for that direction. There are procedures to authorize trains to run opposite the designated traffic flow on a track.
Even on lines with heavy traffic, railroads can find or make time windows for switching operations.
Today many (perhaps most) double track mains are signaled for bi-directional operation on both tracks. The Dispatcher choses which track a particular train runs on to make the most efficient use of the facilities regardless of direction of travel.
