It depends on where you think your knowledge is lacking?
There are a number of things you need to know to get reliable running:
Keep your track as level as possible.
Joints need to be tight, with a little 'conductive grease' and / or clamps.
Aviod twists. - Especially on curves, or points (turnouts).
Avoid gradients, if possible.
That type of thing..
Frequent running, will help keep track clean, so power pickup remains good. - If track-power is bejng used..
Don't run too fast. - This is supposed to be relaxing!
Listen. - If something makes a strange noise, is it supposed to?
Does the controller smell hot? - A controller sat in the midday sun, is a recipe for disaster.
If you have tight curves, run your trains in opposite directions. - This will even out the wear on things.
If you are not sure about something, then ask..
The worst is we can say we don't know.
