So following your logic Herb, one in four aren't human ?
(thinking about it that could be about right !)

Lovely photos Herb and an interesting looking bogie hopper (gondola). Stub switches - fascinating things, unknown here, but presumably only for very low speed use & short wheelbase cars & locos ?. Presumably something like a Consolidated couldn't manage the rather abrupt change of direction ?.

Happy Christmas & no doubt a wee dram or two for Hogmanay.

Regards Michael

PS: Have you any idea please Herb (just off the top of your head)(that may be an English colloquialism ? i.e. don't waste any time)roughly what Switch Number, Angle of Departure or Radius that East Broadtop stub is ?.

On the EBT photo, a Consolidation is just passing by and no doubt it can negotiate a stub. IIRC from my last trip ( admittedly a few too many yrs. ago ) the frog was no. 7 or 8. From there always a curved rail goes to the moving yoke(?), so the actual deviation angle is not that much ( you move the rail by 4" at most )

P.S. So your wee dram is 10 regular fl. dr. then?

Correct about the large locos on the EBT, Helmut. Actually, they are 2-8-2's, the only steam that the railroad had from the 20's on. The most curved track, to the left, goes to the turntable--although there is another route.

And from memory. (not much left what with all that coming off the top of my head [US also]) I would say that you are pretty close on the frog angle.

There was another B&W photo posted here a couple years ago of a similar stub switch--which for want of a better name I will call a single slip--in a different location. Both photos were taken (I believe) in the era of the War of Northern Aggression -- (AKA-"Civil" War--an oxymoron if there ever was one) 1860's when running rail was probably about 50-60 lbs/yard. Most of the main trackage on the EBT is 85 lb rail, but something tells me that the EBT switch shown might be 60. I doubt that the switch shown couldbe"thrown"--bending 4 rails instead of the normal stub's 2--with much heavier rail. Even so, must have been a grunt to throw.

Interest fact about the EBT rail. The Tsarist Russian goverment placed a large rail order with a US steel mill, and as I recall (reading--I'm really not that old) one shipment was made. Then the revolution came and the mill didn't get paid and with no reason to believe that they ever would, put the rail on the market, probably at a discount price. Seibert, the EBT president who rebuilt the line to much higher standards, grabbed the rail up and relaid the whole line with it. The rail has a non-standard cross section, however, so only the fishplate (rail joint bars) made for this rail will work.

@Herr Bert
Those rails weren't flexed after all. You moved the whole assembly of two parallel rails in a frame that slid sideways in accordance to the switchstand's throw, forming a parallelogramme this way. So the elbow grease needed was not more, but less than for nowaday's turnouts. ( Provided they used the other grease on that turnout, too )

Mike Blazek http://blazeksplan.com/ has a wealth of information about many of the NG RRs in Colorado. I gave used several of his notebooks of D&RGW yards, depots and other locations on the RR when I was working in HO. You might look at his web site and see if there is any material that will help you in your quest for accuracy as well as modeling information.

Helmut: No doubt the Southern Gentleman's measure will be 10 regular US fl.dr., on the basis that the Colonial measure is larger than an Imperial fl. dr. !!

Herb & Helmut: Many thanks for providing such useful info purely from memory - obviously you both have non-age impaired total recall ... Sorry, what was I talking about ?.
Dare I try a 3 way stub in 16.5 mm after years of 32 mm gauge ?. Could be fun even if too anachronistic.

Thanks Bill, I'll look up your suggested link. (I have just looked it up,it's all "Pay for" - I don't even spend that much money on Mrs Salada unless I'm in deep s**t !).

Regards Michael

I generally do not accept challenges unless accompanied by the promise of a large bottle of >40 deg. - & I NEVER accept a challenge on this 25th of all days !! (unless perhaps accompanied by 2 or more bottles).

All I asked was a simple, innocent question about typical S/West US NG yard design & suddenly it's high noon at the OK Corral with Herb/Woodie unleashing some impossible weapon of modeller's destruction. Seriously, that is one fantastic looking bit of kit - I take my hat (& wig) off to you Woodie !.

Luckily I've already said I ain't doing the trackwork yet.

Helmut: that looks to be an excellent link, Thanks.
Herb: Also my thanks to you - I'm now wondering, could I?.

Regards Michael

Remember: Keep it PC in 2014 (but only for track ties).

Michael, we're not done messing with your head yet ---



This from a very good friend Dwayne, who posts here on occasion.

Now, I have no more info on this than what you see.

So gentlemen, we have five. Can  I have six?  Six? Six anyone? Going at five. Going once, goi........
