the army unit is yet another version. nose headlight, oxyoke air filter, original cab. this one appears to be a Paducah rebuild as well.

another modification often made when rebuilding was the removal of dynamic brakes on units that originally had them. db was unnecessary as most gp10 rebuilds went into yard and local service where speed were low and dynamic brakes less effective. often the fan and air intakes were removed from the dynamic brake housing and the openings plated over.

as an example of how varied these rebuilds were, consider the 3 units on the Pittsburgh & ohio central. all were bought second hand. 706 has an ox yoke type air filter and a bug eye headlight that protrudes above the short hood. 1711 has undergone its second rebuild. in the first one it got a lowered short hood, an ox yoke air filter, but retained its dynamic brakes. the headlight was moved to the cab roof between the number boards, similar to the walthers gp9m. in its second rebuild, the entire db housing was removed, and the radiator fans were changed from the single large button top fans common to late production gp9s, and replaced with the fans from a gp40. the third gp10 was rebuilt as a "gp11" with a cab similar to a gp40, ox yoke filter and no dynamic brakes. the headlight was moved to the nose of the unit.  all 3 of these were done by Illinois central at their Paducah shops, though they were done for different onwers.

In the past, I have come across an excellent YouTube video of how to do just what Mr. Ward suggests with the turnout, on a traditional turnout/switch, but can imagine it would be a little more difficult to do with EZ track since the roadbed is already attached.

it wouldn't really be any harder than with any other switch. you'd simply drill down through the roadbed and loop your wires up to the rails from under the layout. just the same as you would with a soldered feeder wire.

or, as a precautionary measure, you could solder those jumpers in place before you lay the track, and only route them under the plastic roadbed. an ounce of prevention......

that day is closer than you think. blue rail trains is offering a combo decoder and removeable battery that is designed for use in scales as small as HO. the battery is designed to be charged in a charger that I believe is commonly used in the RC world.

the main hurdle left to overcome is how to charge from the rails, without overcharging and damaging the battery.

if you did have a short due to a reverse loop it would have shut down the layout so that nothing would run. this would be true dc or dcc.

a more likely scenario is that your locomotives are losing contact on the switches (turnouts)

one of the most common things that happens is that the points lose contact with their adjacent stock rails, making the entire switchpoint a dead spot. this is easy to confirm with a multimeter by taking voltage readings between the switchpoint and the opposite rail. the voltage will read the same as the voltage across the rails on a regular piece of track. if it reads 0 you have a dead point.

fortunately the fix is pretty simple. solder a jumper wire from the point to the adjacent stock rail. be careful that you do not accidentally solder the hinge on the point so that it no longer pivots, it is best to solder your jumper to the inside bottom edge of the point, maybe 1/2 inch ahead of the hinge, and route the wire under the roadbed to the stock rail. you can make your connection anywhere on that stock rail, but solder to the outside edge of the rail. since you made your joint to the point on the inside edge where the wheels run, you may need to carefully file the solder away to clear the wheels.

the problem here is that the gp10 was not a standard model. there were many different gp10s rebuilt by different railroads, and all of them were different. walthers already produces what they call a gp9m, which would make a good generic model of a gp10.

before you purchase a dcc system there are several things you should look for.

1. can it do basic programming, other than changing a locomotive's address.

2. does it have adequate current capacity to run more than one locomotive? this is especially true if you intend on running sound equipped locomotives, which can draw a lot of current.

3. can the system be upgraded? can your basic controller be used as part of a larger system if you decide to upgrade? are extra throttles available for this system, or can it use existing dc power packs as extra throttles?

for me personally. any system that does not meet all three criteria will not be considered, regardless of cost.

does the dynamic brake feature work on bachmann with dcc sound? If so would the unit have a winding sound when operating in muted mode?

Dynamic brake is not a feature of a factory installed Sound Value decoder in a Bachmann HO ALCO S4.
that is probably because few, if any, alco s2 or s4 units had dynamic brakes. in fact, only a handful of switcher types ever had this feature.

ez track offers 22r, 26r, 28r 33.25r and 35r. atlas has 24r sections as well. there is a good selection of larger radius track readily available.
41  Discussion Boards / HO / Re: Dash 8 40 ? 6 axle and curves on: September 19, 2016, 08:24:35 PM
two things.
first, the 6 axle dash 8s are too big for the 18r curves that come in the train sets. would suggest that you use 22r or larger radii.

second, there is no such thing as a 4 axle dash 8 c. all 4 axle locomotives are by definition b trucks, not c. the 4 axle version of a c40-8 is a b40-8, which was made by walthers. if that is what you have, yes, it will negotiate 18r curves. it is also a much shorter locomotive than the 6 axle versions.

I remember him......another one that seems to have disappeared.

Jim.....look at this page. https://www.walthers.com/caboose-industries

I don't know how you get the N ones to work with that little of drawbar movement. Do you relocate the attachment point? I know I tried using HO ones on N turnouts when I was playing around with the HOn30 scene......never could get them to work and had to swap for proper N scale ones.

If the drawbar travel is too little, I don't see how they could successfully throw the points. But then again....what do I know?



Sid

sid,

is you want to adjust the travel in the points, it is a simple surgery to replace the throwbars with a strip of pc board, and solder the points to this. you can adjust the points to suit the switchstand, rather than trying to adjust the switchstand to the points.

consisting is a function of the command station, not the decoder. thus, any decoder should be able to consist with any other regardless of brand.

you will probably want to speed match your locomotives before you consist them, if they run at significantly different speeds. by adjusting the faster one to run at the slower one's speed you can eliminate them fighting each other while in consist. this is an adjustment that can be done to the decoder by adjusting cvs 2 5 and 6.

for me, the easiest way to do this is to time each locomotive over a set distance, calculate the speed percentage of the slower locomotive relative to the faster one, then adjust the values of the cvs downward by that percentage. to do this you need a command station with readback capability.

as an example, say one locomotive takes 30 seconds to complete a loop, the other takes 40 seconds. the slower locomotive would be running 75% as fast as the faster locomotive, so you would reduce cv5 and cv6 by 25% on the faster locomotive. this should get you in the ballpark, and you can make further adjustments in the values as you see fit.
