=====Guide:Track Control for Beginners=====

Here are some track direction control ideas for those who are building transportation systems.
I heavily use [[Track:boarding_track|Train Boarding Tracks]] in my design so that I can stop at various places in my underground rail system.
Quick review of how the boarding track works:
| 1) The cart approaches the Boarding Track. | {{ :screenshots:boarding_track_explanation.png }} |
| 2) Cart stops. it waits patiently until the Boarding Track is powered. |  {{ :screenshots:cart_stops_on_tbt.png }} |
| 3) Once the track is powered the cart moves on its way. I like to use buttons to power the red stone on the floor next to the Boarding Track. |  {{ :screenshots:cart_leave_tbt.png }} |

Allright. Simple enough - I can stop the cart and continue. Why would I?

One thing you can now make a subway system with many stops along the route. Each subway station would allow you to stop, and then choose to either get out of the cart or continue.

Another example:
You want to stop just before a switch track so that you can choose which direction.
| 1) You are in the cart as it approaches a Train Boarding Track. Notice in the picture that the switch track will turn to the right down the diverging  line. You'll also notice that I have the button on the green wool as my trigger to contine (it will power the Boarding Track when I press the button.) | {{ :screenshots:cart_approaches_decision.png }} |
| 2) You stop on the Boarding Track and can choose to go right or straight (depending on the direction of the Switch Lever. You remember [[Device:switch_lever|switch levers]] right? | {{ :screenshots:cart_choice_right.png }} |
| 3) You decide that you want to go straight instead of right. Right click on the lever to switch direction. | {{ :screenshots:cart_choice_straight.png }} |
| 4) Now click on the button will make the cart continue. | |
