Newbie question; getting back into the hobby

Just be sure the electrical equipment you buy will run the locomotives you want.  CLUE: they are not all easily interchangeable.  In fact, I would suggest looking at the numerous threads in the DCS, Legacy and Electrical fora before settling on anything.  You might decide to buy engines that come with their own remote controls and a wall wart that plugs in to wall and track, negating the need for a brick or a remote commander.
