Way back when, wood boxcars often had small doors in the end to assist loading lumber and similar long loads. Of course, there were no fork lifts to worry about then, either. Fred W ....modeling foggy coastal Oregon, where it's always 1900....
[quote user="bear's lair"] I am modeling a late 1930s west coast logging rr in ho scale steam powered, with lot's of inclines with mountains and hills and a large forested area with two trestle bridges on about 95ft of track, [/quote] You didn't really define a prototype, or what a good model locomotive means to you - other than durability and weight. How important is prototype fidelity? Slow speed performance? Does it need to be quiet enough to install sound? What level of
[quote user="jecorbett"] At this point, I'm willing to try just about anything but I'm trying to understand exactly what you are suggesting. Is it possible with a single switch to both change the routing of the turnout and the polarity of the frog rails. If I hard wire the frog rails, it seems to me the polarity must be changed simultaneously with the switching the point rails or else a short will result. Exactly how should this be done? [/quote] As Jay stated, you actually have
[quote user="mreagant"] Are you sure that the brush will scratch the drivers? The brush looks to be copper or copper alloy which should be softer than any ferrous metal alloys used in the wheels. If so, shouldn't scratch. [/quote] The drivers (except for Athearn BB) are not ferrous metal alloys. They are usually nickel-plated brass, plain brass, or nickel silver (all copper alloys). We'd have more tractive effort if the drivers were stainless steel (and slightly less susceptibiltiy
Are you looking for a generic layout - or do you have a vision of a particular region or scenes in mind? You talk about 1950s passenger cars. What kind of radius are you comfortable with? Will you run shorties, like Athearn, on 18" radius? Will Rivarossi or AHC with truck mounted couplers suffice? Or do you want 30" radius with Walters cars, no modifications? The radius is going to pretty much control the layout shape, especially with a continuous run mandated? What kind of operations are
[quote user="cacole"] Any controller that uses a light source, whether photocell or infrared, does not need resistor wheel sets -- only controllers that rely on current sensing [/quote] To expand on what cacole wrote, there are significant differences between optical and current detection sensors besides the use of resistor wheel sets. Current detection detects a train's presence in a block of track, but doesn't localize it any further than somewhere in the block. Resistors are
I like to use Atlas sectional track (or any other brand of sectional track from train sets) as a starting point for my small (4x8 or less in HO) layouts. I use full curves for any curved areas of more than 30 degrees curvature. This allows consistent radius curves on the ends of the layout. Flex track is used on any straight sections, and in any area with less than 30 degrees of curvature. Atlas flex and sectional track matches just fine. Cut the rail lengths of flex to fit with rail nippers, and
[quote user="markpierce"] [quote user="Allegheny2-6-6-6"] I thought painting the roadbed ballast color was a good idea but as brought to my attention by California roadbed co. it is not necessary in their case as it comes a gray color and my mainline ballast is gray so painting it only make sit hard and less sound absorbent [/quote] That's interesting, since the original manufacturer of Homabed recommended the roadbed be painted to reduce problems with possible moisture absorption
Actually, the Atlas Snap Switch is not a numbered frog. It is a 20 degree piece of 18" radius curve set 1.5" in from the end of a 9" straight. The frog is curved and plastic. Atlas CustomLine turnouts have straight frogs that are numbered. The #4 is 12.5 degrees instead of the 14 degrees of a true #4, making it less sharp. The curved portion of the turnout has a radius of approximately 22" to 24". The #6 turnout has a 9.5 degree frog angle (Atlas rounds it to 10 degrees in
[quote user="cacole"] I don't know a source, but for that many machines thrown simultaneously you'll need a supply with a current output of around 10 Amps or more. The old NJ International and Tenshodo machines each draw 2 or 3 Amps to throw, and if the power supply can't handle that much load they won't throw. [/quote] Cacole You are right if we talking about the rating of a standard power supply. A CD unit stores large amounts of energy in the capacitor(s). When the button
