[lua] Train station program

On a multiplayer sever we have a train station.

What I want to do is for a monitor to display how far away a train is and say when it has arrived.

I have thought of a couple ways to do this but need help to decide the best choice.

Also note I am using FTB direwolf20 pack so misc peripherals is installed.

Option 1-
Use a detector rails and have separate wireless Redstone frequencies for each detector rail that represent a certain distance from the station. Then near monitor have a turtles with a Wireless Redstone module and wireless modem attached to them. There would be 1 turtle for each frequency. Each turtle waits for a Redstone signal through wireless Redstone module and then sends the distance cart is over rednet to the monitor.

Option 2-
Use detector rails and frequencies again but have each frequency output into a certain colour that goes into a bundled cable which attaches to a computer. Each colour would represent a certain distance. The computer waits for signal through a colour. Then converts that to a distance and sends to monitor to be displayed.

These are the only two options I could think of so if anyone has a better way of doing it that would be great!
I hope both methods make sense! :P/>
Thanks!

I'd probably use the bundled cables.
In both cases, if you have very long tracks and put many detectors, it will be demanding for the server.

I'd suggest going with bundled cables too, but like imef says, it may be demanding if you have a lot of distance sensors to probe.

thanks for the reply guys!
Okay ill use bundled cable method but I won't use too many detector points :)/>

i havbe built a train station too and the way I did it was to tell me when a train arrives at a station a station and when it leaves a station. I wanted this as i am working on a program where i can control the whole system so a train could be at a station and from the computer at the control room i can send a redstone signal to allow the train boarding track (from railcraft) to be activated and let the train go. I did this by placing detector tracks down at the station with a computer underneath it which basically waits for a redstone signal, when it does it sends a message to one computer saying "train is at station 1" for example. Then when the redstone signal turns of it sends a message to the same computer saying "train has left station 1". This way i know what stations are occupied by a train. I used rednet to send the message and just changed the rednet sending limit in the config file so i didn't have to mess around with extra computers to relay the message.
