Hi,

My last experience with model trains was an A. C. Gilbert American Flyer steam loco
in the 60's. I recently became fascinated with the UP Big Boys.  Long story short,
I have decided to build a G scale outdoor line based on an MTH One Gauge Big Boy.
I have my pre-order in for the next production run, and in the meantime am
designing/building the dead rail specific parts using an MTH HO scale Big Boy.
I have a running model using the MTH TIU (track interface unit) and MTH WIU
(wifi interface unit).  I have removed the TIU from its original case and am in the
process of placing it into an MTH RailKing One Gauge 40' boxcar. I hope to get the
WIU and a Pi3B+ in the same car.  I will use a 2nd boxcar for the batteries. Will
take this to the point where everything is contained in the 2(3) boxcars, without
any external cables except the power/control pair.  It will be attached to the track
during HO development, but when the G scale Big Boy arrives I will remove its power
wipers and attach the cable from the boxcar directly to the Big Boy. I chose the wifi
route as I have a fairly large acreage and will eventually years) be able to run a
distance of 1000' or more.  I plan to use a DD-WRT mesh wifi network to cover this
distance properly.
 
My work so far is documented here:

Hey there!
That control system is beyond my knowledge and experience.
Went and looked over there. Grades, oooohhh, grades. Be very, very, very, careful with grades.
First: a note because of what happened at our model train club a few years ago - grade percent, and angle degrees, are NOT the same thing.
Second: in a book about MILW on shelf across room from here it mentions a place where Milwaukee's electrified section paralleled Northern Pacific at some point and the NP was on a 4% grade at that location. An NP Mallet of something-8-8-something wheel arrangement was rated 600 tons on the 4% grade - that's only six, count 'em, six, modern 100 ton grain hoppers.
From a book which is not as buried in the stack as the MILW book a Baldwin Locomotive Works Class 20-46/74 1/4 - EE Mallet 2-8-8-2 with 57inch drivers, 405,000 pounds weight on drivers, 200lbs boiler pressure, was rated;
9975 tons cars and lading on level
2930 tons cars and lading on 1% grade
1020 tons cars and lading on 3% grade
525 tons cars and lading on 5% grade

And remember, a grade on a curve has same effect on pulling ability as would a steeper grade.

Hi Steve :wave:



WELCOME ! again to Freerails !!

Great to see you here on the Site.



It would be nice to see some photos of your project ...

... and perhaps a Thread to follow your progress.











Some photos of Steves current work on his unusual approach to radio-controlled railroading.

I'm sure he'll tell us more   .   .   .



All the best Steve. :)

Oh, and remember that with indoor scales the transition between level and grade needs to be gentle, a couple feet long; whereas on G scale layouts that translates to several yards or meters long.
A component of the reason is so that you don't get vertical displacement and disconnection or binding in your couplers.
Another reason for that is because long wheelbase steamers don't have accordion folds in the middle of the boiler.
(well, not except for that one design the Santa Fe tried but that's another story ...)

Forrest,

That was another topic on my mind. The mth specs talk about R3 curves, but not anything
about the "curve" in the vertical plane. Sounds like your saying the transition
from 0% to 3% grade would be 6' long?

I assume you would use "flex track" to do this?

Hi,
It was suggested in the membership mailing that I start a new thread on my project.
What would be the appropriate forum?

I'm thinking "R. C. Control - The future is now if you desire".
Perhaps a topic of: "G Scale BigBoy via WiFi"

Hello again. I can't give numbers to use with a garden railway since I've not built one as my upper floor apartment is a bit short on garden space. Mike and Mary, now retired and moved away, had a garden railway built before I met them and the way they built it on sloping ground the exact points of transition from level to grade (think they had about 2% in one spot) were inexactly defined but were at least as long as an adult lying on ground next to track. Mike was in to geared steam and transition era diesels so he could get away with sharper vertical curves than could someone running oh, say, UP's 4-12-2 three cylinder jobs.

For some things my brain works better in relative proportions than in numbers so here's what I will say:
for a garden railway running mainline style trains, make your vertical transitions gentle and about the length of 3 Pullmans or 3 auto racks.

Oh, almost forgot, yes, flex track is a good idea, as was told in rhyme about both horizontal and vertical curves by an old-timer; rail joints are kinky points.

 Hi Steve :wave:



That sounds like a great idea, to document your Wi-Fi project in the 'R.C.' Forum. :brill:

Perhaps a 2nd Thread in the 'Large Scale' Forum, could deal with your track & outdoors planning/building. L:



It's entirely up to you Steve. :)



If you want a Thread MOVED to another Forum at some point ...

... or RE-TITLED latter, for whatever reason ...

... just give me a shout & it can be done. :thumb:

Hello again, again, yet once more. "This just in!" as they say in the news business. Question: are you wanting to make use of garden railway trains' ability to run in rain and snow?
Then the fewer grades the better.
Those weather conditions have negative effects on adhesion and tractive effort.
(and on electrical conductivity if using power from rails)
