Well, the train house is nearly finished on the inside.  Others who said they would help did not, so my wife and I have been using weekends to get it finished up.  Only have a few more trim items to attach.

I placed the layout on the floor to see if anything needs to be tweaked.  Also going to connect the two loops.

Nice Train building! I also like the 1:1 print out idea. I was thinking about doing that but wasn't sure if it would be worth the paper and ink! I might revisit the idea!

The paper isn't too much of an issue, Mike.  It's the ink that racks up the cost.  If we just want to print the track, in black ink, it might not be so costly.  

Russell, That is a great looking building, nice track plan, and I like how you have it printed out full scale too!  I'll look forward to seeing more now hat I saw this topic.

As far as lifting or dropping the bridge goes, pnumatic cylinders much like the automotive hatch shocks could be used. It doesn't take much air to use them and they can lift a lot. A small compressor from a car with airbags likely wouldn't even need a tank.  The fine reaction speed is as simple as an adjustable valve similar to that on fish tanks air lines.  (try looking at Bimba cylinders. Try a Parker Store too. Get rebuildable ones if you can).  Low volt control solinoids for pnumatics can be had too. (Mac was my fav, rebuilable)  Pnumatics, various pressure valves, and flow limiting are what gives the better animatronics the lifelike movement characteristics, but with soft stops, etc. (when tuned right anyhow)

  I like pnumatics because they are strong, yet not as destructive as a geared motor might be "worst case".  Same limit switches, etc would apply.  I'd only really consider a stepper motor in place of air. 

Very nice depot.

Nice idea, printing the layout out full size.  How did you manage that ?

Dan,

1:1 layout printing is a feature available in SCARM.

Wow!  What a journey from the basement of the other house.  Russell, after all of this work on the train house, the layout will be a easy task. I think you'll need an "official" sign for the depot.

I would suggest that you try to fit a "kill" track between the switches that join the two loops. Then, you can still operate two trains conventionally or one train on two loops. Some insulated pins, a short cut of straight and a toggle switch would do it.

Thanks for the input on the layout.  Carl,  can you elaborate on the kill switch you are talking about?  He has a Lionel transformer that operates up to 4 different circuits. I have been trying to figure out how to do the switch thing between loops and cant seem to put my head around it.  We will need to have the loops operate separately, which is easy enough, but operating with the loops connected with a smooth transition between loops seems to be more complicated.

Adriatic,  I like the idea of the pneumatics, I'l have to explore that further.

Russell,, here is a pneumatic lift bridge I built. If you are interested in more information let me know!

I didn't know you ended up with pnumatics Mike. Very cool; nice and slow too. A tank would be a few minutes buzz then silence till the pressure goes low. (and I do mean silence)

Do you plain to run long freight trains?When I say long I mean 25 to 35 boxcars.

Ok, transformer channel 1 operates the outside loop. Transformer channel 2 operates the inside loop. Channel 3 is trolley.  Channel 4 is Accessory power fixed voltage.

The two loops are isolated by cutting a small piece of track, say 3", to place between the switches for the crossover. A Plastic O27 pin is used in one end of the small straight, on the inside loop side.

Now the power does not pass between the two loops, permitting two train operation with separate handles.

A simple toggle switch (On/Off) is used. A wire from Transformer Channel 1 is connected to one pole and the other pole is connected to loop 2 center rail.

For Transformer channel 1 to operate 1 train on both loops, Channel 2 is moved to zero and the switch is placed in the On position. Now Channel 1 controls the entire layout.

It would also be helpful to have kill switches for the passing siding and the two spur sidings to provide a place to park a train and engines and not have them run.

I could create some diagrams if that would be helpful.

Carl,

THanks for the explanation.  I'll go with that and when I get to wiring, I'll likely need more help.  Dad is going to order Mianne benchwork. We are going to go with 3/4 plywood with homasote glued to it. Track will be attached to the homosote.

Seaboard, I doubt Dad will have that many cars on at once.  Probably 10-15 at the most.

Mike,

I like the pneumatic bridge.  I'd love to get the info on it as I think Dad would like to use it.

Thanks,

Russell, shot me an email and let me know what information you would like. I have sent it on to another forum member getting mianne bench work to use with it, he sent it on to Mianne so they could hel with the build.

I agree Mark, but it wasn't my idea. I guess I should have put a copywrite on my design LOL! I sure hope they can help the other forum member out!
