    Hi Dave,

    I’ve sent the latest ‘draft’ version of the layout to you through e-mail. I’d be happy to discuss the nuts and bolts of it with you once you’ve seen it in operation.

    Regards, Chris

    Hi Chris,

    I can’t tell wether you’ve had lots of experience programming in BASIC

    or program PLCs or both or neither! I can, however, tell that Thats a pretty impressive application of controll logic! Boolean Algebra.Wow,

    Could it be from solid state circuit design?

    Also, those are pretty snappy looking stations you have there.

    Nice going!!!

    Hi Mark,

    Thanks for your comments. I’ve worked as a software engineer for a number of years.

    I’ll do my best on modelling a station based on those examples. Brainbom is over-commited at this point so I can’t give you any idea when it might be introduced into the game.

    Best regards, Chris

    Hi Map,Chris and Dave,

    It´s not only in BASIC on pc,the sps is the same. And Chris is creating a sps with these tracks. See what brainbom says to this pics and explantation.

    may be bb will implement a ec as tiny BASIC 💡 :?: 8)

    Hi Chris,

    No hurry on the stations. I’ve seen your work and know that it is worth waiting for. I’m just having fun posting pictures. If they can be of any use to someone, so much the better! As I said, if there is anything up at this end of the country that you’d like to model and need a picture of, let me know.

    As for the controll, have you considered developing a flowchart & logic/truth table for planning a control point. If predetermined control sets for specific movements could each be assigned a “command” each compex routine would only need to be worked out once and then individual “commands” could be linked into a program of sorts.

    But my guess would be that You’ve allready been there!

    Thanks and have fun…

    Hi Mark,

    Formalizing it as you’ve suggested would ease layout modification/expansion not to mention making it clearer to someone seeing the operation for the first time. Right now there are about 21 blocks on the mainline (a block is about the length of the longest train on the layout). Since each train modifies the three trailing blocks – off, a percentage of the ‘legal’ limit, and the ‘legal’ limit – I should be able to have seven trains operating on the main line at any one time with a train waiting in each siding.

    There’s a certain randomness to the operation – adding or removing freights and passenger trains seem to change whatever pattern establishes itself. That randomness is something I’m going for since it helps maintain my interest.

    I’ve left myself some expandability as well. I’ve thought of putting in an interchange that would lead into a local short line for switching operations.

    Thanks for your suggestions.

    Best regards, Chris
