When you have got your track fully tested with the locomotive at various speeds and directions, you can now rezz a complete train onto your track. There is a rezzer provided with each train set. This is to simplify the rezzing by doing all of it at once. You can of course rezz all the vehicles separately should you wish.
Place the rezzer onto a straight section of track. the train will rezz in the direction of the red arrows. It should also align itself with the loco and space its cars out correctly
Click the rezzer once and the train should rezz its loco and cars.
After they are rezzed they should be aligned correctly in a straight line.
If they are slightly off the track they will correct once you drive the train off from the rezz point.
The cars should follow the loco around the track. A medium speed gives the best results.
