I dont know what sprog and arduino is but i assume its cheaper.
For the direction sensors just define a bunch of sensors in your sensor table. Then when you define each ssl signal place a sensor for the 2 directions where it asks for it in the window that your using. ?They are not actual sensors but placeholders four ssl logic to use. ?I use ssl signals on jmri. ?No physical signals so they dont add cost.?
Most people using automation claim sml signals are better. ?If i remember correctly sml are not placed at switches. ?When have switches in the block It causes the train to stop a block further than the signal is. At least thats what happens when i tried sml.
Using ssl if block 1 is occupied then block 2 behind it is where the train following it will stop. Thus with only a 6 block loop and setting allocations it 2 instead of 3 you can get 2 trains running on that loop.?

?Hi Tony, ? The cost element of the extra hardware hadn't slipped my notice and I am having to build my system with cost restrictions just to prove to my wife this isn't a whim, so using Sprog and Arduino with both current sensing and optical sensors,? I was partially driven to re-think the turnouts and blocks issue when I tried adding signal masts as jmri wants to add them to boundaries to blocks? which works fine when the turnout is a separate block, when I tried SSL Dispatcher need sections to have directional sensors? so that bamboozled me .
Thanks Steve
