computer controlled

Legacy is better, more sounds in my experience. Smoke is great though on both.

I wonder if this is a job for JMRI?

I immediately figured DCS or Legacy would suffice but I don't know that they can limit speed and check for clear tracks ahead. Legacy does have accessories that can record a sequence and play it back I think.

But it sounds like you're looking for logic paths and stuff and I think that's the domain of JMRI. Maybe somebody else can comment on that?

You might want to check out the new forum sponsor, Scaled Automation.

One problem I see is that some of his trains are conventional...they would have to have some type of controller installed.  Legacy does have some great abilities to record sequences.  My concern is that the recorded sequences for each consist may not mesh well, so John may need to limit the number of trains being run at the same time.  A lot of what John has mentioned is on my "this is what I want to do" list.  However, my model railroading time is becoming increasingly limited.

I've gotten some flack for my on screen controller (see attached), but it can be resized and it's fairly obvious in its usage.  The resize feature is definitely helpful to the eyes as well as control.  I think some of those concepts are needed for those with disabilities.  Even I have trouble with the MTH controller.

I'd be eager to see what solution, if any, John is able to implement.

I want to thank everyone for the input. I am going to look it to , Scaled Automation.

Thank you

Keep us posted!

I contacted Scaled Automation and there replied "John:

I am still looking and will keep you all posted. If we can fly to the moon and back someone should be able to help with this.

John,

I admire your aspirations.

In the real world (1:1 scale) what you're asking takes a great deal of what is generically called "infrastructure", a significant amount of software for user interface and control, and a great deal of detailed testing to make sure it works correctly before making it operational.  It's important that it function correctly to be safe to the trains being controlled, the people on them, and those on the ground that the trains will encounter.

You would think that doing it on a small scale would be much simpler than in 1:1, but it's actually no different, especially for the user interface and control software, and only slightly simpler for your small-world infrastructure.  The thing about making a small-scale world that mimics reality is that the control you seek is just as complex as in the real world -- in fact the software and user interfaces needed for your layout could easily be transported up to 1:1 scale afterward.  This is often done in developing complex solutions to real-world problems.

One consequence of so many kids having and playing with toy trains back in the day is that a large number of them became technical professionals who in their careers aspired to solve these kinds of challenges, starting with what they learned with those trains -- myself included.

My feeling is that what your asking is still too much for present-day model railroad enthusiasts and suppliers to handle, at least currently.  Yet, we're all  are on track (no pun intended) to make it happen, sooner or later.  Continue to ask questions and contribute.  One day, relatively soon I think, you will be pleasantly surprised to see it actually occur.

Flying people to the moon and back was, and remains to this day, the most complex control task ever accomplished.  Unlike many situations where the general public cites its success as proof that we should be able solve whatever problem they have, your request in this context is more appropriate than you may realize.

Stay tuned.  This forum is the perfect place to be.

As has been mentioned, one main stumbling block is your inventory of old and new locomotives and command systems. There just aren't any off-the-shelf computer automation systems I can think of for three-rail O gauge.

However, the level of automation you seek is regularly done with Marklin command systems and trains, for example. The ESU ECos system supports automation as well. JMRI has been mentioned and there's also iTrain, RocRail and TrainController. These are all software packages that can provide a high level of automation, but they work with DCC (Digital Command Control) and engines with decoders inside, not post-war Lionel. Also, in order to get what you want, you might have to invest a significant amount of time programming and configuring the software. And you'd need new locomotives, the command systems, the software, detection hardware and so on. But this would be less expensive than custom software to automate your current inventory. Maybe start small with two ovals, three trains and a passing siding, or something like that.

If you want to set something up fairly quickly so the children (even if adult-sized) can watch the trains run, then take a look at another system. There are support forums on groups.io and marklin-users.net for all of this stuff. There are a number of automation examples on YouTube as well.

Thank you and I will look in to this

I have a new layout with 7 tracks with Radis from 036 to 084. I am looking for the best system to run my whole set at one time. Lights, 25 022 switches, accessories, and trains from post war to present day. I have about 50 different engines, half are post war, and the other are lion chief, and legacy.

How exactly are you 7 tracks arranged?  Perhaps you could meet in the middle by having postwar only loops and command only loops. That might solve the mixing problem between the two types of locomotives. Then you can start looking at your options for logic controls or take advantage of Legacys ability to record actions.

What I mean to ask is, do you have a track diagram that we can see?

I had two other thoughts:

- The most popular scale for DCC trains is HO. You might find this scale too small. The engines and cars are wonderfully detailed, but best viewed at eye level. I find the figures and people to be tiny. However, the large scale (G gauge) trains also run on DCC and are very entertaining and robust. They are as expensive as new O gauge locomotives, which is to say, pretty expensive. Many folks run these trains outside because they're big, but I run mine inside in a 10 x 16 room. Lots of impact, lots of noise!

- With Lionel Legacy locomotives, you can use the Sensor Tracks to program stopping and starting at stations, blowing the whistle, etc. You could use signals tripped by infrared sensors. They wouldn't actually do anything, but the lights would flash and change as the trains rolled by. With this option, you could do away with most (maybe all) computer control yet still have a high degree of automation and still use some of your current rolling stock and track. Check out Lionel LCS (http://www.lionel.com/lcs/).

I didn't think of it till I read this but you could look into the use of infrared sensors with an Arduino to flip blocks on and off for your postwar trains. It would be a pretty big undertaking but I've seen IR sensors used for this kind of logic in scratch built coal tipple operations. They sense the car passing through and won't let the tipping begin unless it sees the right sequence of spaces.

Yes, it could be done! There are a couple of Kindle books on model railroad automation with Arduino. Not exactly "plug and play" but not that hard either if you know a little programming. I think you could find the electronics in Arduino books and magazines. I subscribe to the "arduini" group on groups.io which is all about using Arduino on model railroads.

You can get Arduino info everywhere! It's great. The library, Youtube, the internet in general. You got a good shot at getting it figured out.

Thank You

I am looking into Lionel LCS and a company called Train Brain (TB by CTI) to complement it. TB has a lot of different sensors to tell speed, location, and control of the train and the track loop. The TB system would take a lot of sensors to do the things I require. You have to write code to work this system and this is something I have not done. Challenges or adventure - yet to be seen.

What would be nice is to have an Open Source Solution that anyone can contribute too.

I'm working on something similar to this, that will eventually be open source.  But like has been said earlier, this is a tall, tall order that needs a lot of "infrastructure".  I'd like to eventually get to fully automated layout control, but I'm starting with the building blocks.

I started by replacing all the electronics inside one of my engines.  On an early-2000s conventional loco, stripped out the e-unit, sound board, and lighting.  I'm replacing them with my own microcontrollers, lighting, soundboard, adding a smoke unit, etc.  I'm a professional software engineer and an amateur electrical engineer, but it is a LOT of work.

You can see a video of an early prototype running here:  

I've miniaturized most of the components since then.  For example, here's the current best prototype of the sound unit:

It's based on an ESP8266 chip, which is basically like an Arduino with Wifi capability added.

Fun projects!
