I have started the design and for Christmas train for our display. I have contacted many of the PC members who have built one to get their ideas.

Here is a link that has the Build Sheet, how to build a Candy cane car and a 12 vs 6 Volt discussion. I will update this thread when I make changes or additions as I progress thru the build. All train files are prefixed with "T_"

Comments and suggestions solicited.

I have posted a new file to the build site(link is in the first post). It is how to use a computer power supply in your display to get low voltgae power. (T_How to use a computer Power Supply.mht ) Haven't figure out if I need one of these for a train yet, but I am buying used computers at good will for a $1.00 just to get the power supply and switches.

Goodwill here in Phoenix has 1/2 price every other Saturday. I also got some toys, cars, dolls, etc for $0.50 to put in one of the cars on the train.

I also got the cereal bowls for 0.25 to use on top of the waterfill housings on the engine. I will post the beginning of that how to in the next day or so.

I am starting on mine (finally) think I'll head up to the steel store this weekend to pickup some metal to build the frame off of.

My plan is to use a wheelchair motor for the drive assembly, so, going to try to pickup some motors for that.

From what I've read on PC (and the internet in general) a wheelchair motor will pretty much last all night on a good battery.

Yeah, i am going to try 2 kids wheels cars before i invest in another motor. I do have a lawn mower motor as a backup.

I have posted another "T_" file at http://groups.google.com/group/south...displays/files
It is the initial desigh for the switch that will turn on and off the Crossing lights.

Mike - I tossed together a small timer circuit last night - it uses ~$2-3 in parts at the moment (but, my estimated total cost for parts would be about $10-15 and that would also include a 110v output plug on the unit) and it works quite well. I will bring this along to the mini with me in a few weeks.

My idea was a plug in devices, with options for two switchs (one on, one off/reset) and a time delay adjust that can be adjusted with a screwdriver. The device would plug in, and would be capable of running an AC output of ~5 amps.

This sounds like a great project, My son wants to build a train too. But, I am trying to pace him a bit.

Well, picked up these today - I'm hoping the'll work!!! It looks like a good price for 2 motors with a gearbox.

Super, look forward to seeing it. Thanks a lot.

Thats what I'm hoping! I'm going to have so much stuff by the mini i'm going to need a truck lol!

I did end up getting a few more parts to play with - I want to have the timer adjustable to 1s to like 2 minutes, and is be resetable by another switch

Well, here's the example circuit - 1.8" x 3.21" - onboard regulated DC power supply. Total parts cost is ~7.00.

I am thinking of having a couple of PCB's made to give it a try!

Since this is currently out of my league, Can I help defray the costs?

I had forgotten about this until I was browsing around tonight.

Model RR Crossing circuit. (http://www.kpsec.freeuk.com/projects/levelc.htm)

Maybe it will come in handy

Humm, those are good also - what would be more useful? a timer, or a flasher? and, if a flasher, would it be say, 12v out, 120v out? I was thinking of the flasher lastnight instead of the timer.

Could also be a "timed" flaser capable of being stopped.

What would really be great is photo cells to turn on and off. I saw one the other day. I sent the guy an e-mail and he has not responded yet. I will find the link again and post it. I think it was for a small RR but could probably be adapted.

Photo cells would be easy enough to do - the more I think about it - the more I'm thinking to have 4 ouputs on the "crossing" solid on, flash 1, flash 2, and bell. I'm also thinking of figuring out how to have gates lowered.

Check out this link. (http://home.cogeco.ca/~rpaisley4/CircuitIndex.html) He is the one that has photo cells and can crontrol more than one crossing, belss and gates. I think we need to do all of the above.

Here is the start of the steam engine. The bands on the boiler are very thin brass strips

To complete the boiler:

1. The smoke stack needs to get cut.
2. The bell needs a housing made and mechanism to make it ring.
3. The two water fill housings need decoration and then permanently mounted.
4. Build the headlight and make it function
5. Add the brass steam lines on the sides of the boiler
6. Attach the smoke stack and hook up the smoke machiine to make it work
7. Then on to the cab
8. Then the base with wheels, drive mechanism and cow catcher

That very close to the one i am building. I bought the toy model i am using at a garage sale.

Out of curiousty - what would someone like to see on a crossing?

Switch? Photo sensor? Bell Sound? 12VAC for flashing MR16 LED's? Arm that comes down too?

I have some idea's for this - they "will" add a bit of a cost - but - would make one heck of a complete crossing setup.

Yes to all of the above. Did you check the link i sent on the PCB like the one your are describibg that is already made up.

Its about the same thing - the parts that are used are pretty much standard - but - I'm looking at a winbond ISD1730 sound chip for the bell sound.

The price should be able to be a bit cheaper, and could be done even cheaper if there's no onboard power supply.

Super, cant wait to discuss it at the mini.

What has happened to the train? Are you still building it?
My son and I were following along and were curious what ever came of it?
Thanks

Yes i am still building it. My wife convinced me to remodel the kitchen so that is taking all of my time for the moment. Thanks for asking.:o

frank, i just got on to this thread, but i read that you were looking at methods of lowering a crossing arm. What about a small electric screw-type ram?

On my backyard railroad, I use a real bell. This is big enough that it has a real gong sound.

Someday I'll finish the writeup on building a half-scale, 4-lamp railroad crossing light.

Great! I am in the middle of a whole house remodel, so I know how you feel about putting the fun stuff on hold:-(

We are looking forward to it's return:-)
