1  Discussion Boards / HO / Re: Road numbers on E60s??? on: August 18, 2018, 08:29:27 AM
I have also combed through whatever Amtrak rosters and photos I could find. Apparently, when they were rebuilt they were renumbered in the 600 series. The only ones I ever saw in person, in 20th street in 1986, were in the low 600s. Nowhere could I find any reverence to E60s above 975.

That's not to say they didn't exist as a fluke. Stranger things have happened when a railroad is in transition. A good example would be NS 7329, a former UP sd90mac. It only wore that number crudely painted with a spray can while awaiting rebuild at Altoona. Plans changed, and it emerged from rebuild as 7319. NS rosters don't show 7329 as a former UP locomotive, but I have photographic proof it existed.

when I used them I did not cover them until after the track was laid. I didn't want any surface imperfections to affect my trackwork. After the track is laid, you can bring the plaster cloth right up to the edge of the roadbed and not worry about having twists in your track (which cause derailments) caused by ripples and bumps in the plaster cloth.

When you say you have no speed control does it just sit there? Or does it take off running at full throttle?

I found the reference to Tru Scale roadbed interesting.

My Dad's layout is built entirely on Tru Scale. We bought the plain roadbed, and laid our own ties and rail on it. 40 years later, it's still in regular use with few if any problems.

I haven't found any roadbed  out there that is as good for handlaid track. But it's almost impossible to find now. I am wondering if i'll have to make my own out of pine moulding.

I know when the MT Washington Cog Railway ran steam, the boilers were tilted forward for this reason. Their steepest grade is 37%.
6  Discussion Boards / General Discussion / Re: Tourist lines on: July 01, 2018, 02:55:20 PM
One thing you have to remember about Cass is that the line has excessive grades and two switchbacks. The line to Bald Knob rises something like 2300 feet in 11 miles which works out to an average grade of well over 4%. there are sections in excess of 10%. There are car attendants on every car, and they work the handbrakes on the ride down to supplement the air brakes.

I would imagine that keeping the water levels in the boiler at an appropriate level on the trip would dictate that the locomotive always faces uphill except for the section near Whittaker station that lies between the two switchbacks. Even though there is (Or was, it's been a few years since I rode the train) a wye about a mile from the top, they tend not to turn the locomotive there.

One of the most interesting rides I had was one where they had a work train out on the line. It ducked into the wye to let us by. That was the only time I ever saw a meet at Cass.

Man. Too much math Shocked😱😂.  I gotta go lay down.😂😂

Not me. I am fascinated by the engineering process.

bb don't pretend to understand what you don't.

What ebt posted is the formula for finding the "Degree of curvature" which is a civil engineering way of expressing the sharpness of a curve. It is roughly equivalent of what we call radius. In engineering, when laying out a curve, it is far easier to mark the curve in 100 foot segments than to find the center point of the arc and measure from there. The center point of a curve may be a mile or more away from where the actual curve is. "Degrees of curvature" as expressed by civil engineers has nothing to do with the total degrees in the curve itself.

As an example, the sharpness of Horseshoe Curve in Altoona, PA is 9 degree 30 minutes. But the total curvature of the arc is 225 degrees. When you look at the curve from the air, you see the 225 degree arc. When you are at ground level, in the park at the center of the curve, it wraps around you on three sides. But if you looked at the track charts (Engineering diagrams) for the curve, all you'd see are notations of the start and end points of the curve, and the figure 9degrees 30 minutes.


Degrees of curvature as expressed by the real railroads and by model railroaders are two completely different things.

Iíve always wondered why model railroad curves arenít measured in degrees like the prototype.


The two methods are apples and oranges.It would be impossible to measure curves by degrees the way the civil engineers do. In their measurement, the degree of curvature has nothing to do with the total arc of the curve. In model railroading, the arc is much more important.

Bear in mind that Terry's photos are using the standard 18r switches with a 30 degree angle of turn on the diverging route. That makes the parallel tracks spaced much wider than necessary, they appear to be on about 5 or 6 inch centers. By using #4 or #5 you should be able to tightn up that spacing considerably, even using EZ track you should be able to get the spacing down to 3" or so. Using switches without roadbed, like atlas, shinohara or peco will allow you to space your tracks as close as 2" apart.

That would make sense. IHC was the successor to AHM. And since much of the AHM line was made by Mehano, a lot of the cars later appeared under that name as well.

Though I have 3 shops within about 5 miles. two seem to cater mostly to older train set type stuff. The third puts emphasis on N scale.

The best shop in Pittsburgh, A B Charles, went downhill fast when Bud Charles died about ten years ago,. The son had no interest in trains, concentrating on other things. After a couple of moves under his ownership it is now gone completely.

The nearest shop that has a wide selection of HO is over 25 miles away, in Cranberry.

For me, a shop that just sells locomotives, cars, track and building kits is useless. I need a supply of parts for my various projects. Rail and spikes for handlaid track. Wheelsets and gears for rebuilding locomotives. What I've found is that this stuff is available, but most hobby shops won't special order it. Or if they do, somehow they never actually get it. When I find a shop that actually will stock or special order what I need, most if not all of my business goes there.

My personal wish, something I've asked for on this forum for years, are updated models of the F9 and the U36B. The tooling already exists, and the drives for these locomotives would be the ones used under the f7 and B23-7 respectively.

When I was a kid in the 1970s, every time I bought a ready to run car, my dad would look up the number in the Equipment Register. More often than not, the number either didn't exist, or was used on a car that didn't remotely resemble the model. Manufacturers back in the day didn't do the research to get things reasonably close to correct like they do to-day. A great example of this were the myriad locomotives painted in Santa Fe warbonnet colours. Bachmann had GP40s and U36Bs painted this way in the 1970s. At that time, neither type of locomotive had ever graced the Santa Fe roster, and if they had they would have been in the blue and yellow freight colours. Another example was the 4 bay offset side hopper like the one shown in this thread. 3 bay cars of this design were very common, but the 4 bays were not. I've seen many models of them painted for Pennsylvania, which as far as I know never rostered an offset side car other than a truly bizarre 5 bay experimental car. Even to this day, Bachmann makes these cars in CSX. By the time CSX started painting freight cars in 1987, even the three bay cars were off the roster, and the 4 bays were but a distant memory.

DOes this car have talgo style trucks with horn hook couplers? If so, looking at the method the coupler is attatched to the truck, and the way the truck is attatched to the car body can help identify it.
