How do you know if you need more power to a layout? My layout is 16feet by 10feet with three independent loops connected with 6 switches. I am running DCS powered by a z1000 brick. Each loop is individually wired using 5 drop lines to each buss line. When I run a lash-up at slow speeds (up to 30smph) everything is fine. When I run faster speeds (50smph) the breaker on the z1000 trips out. There are no accessories hooked up to the layout. Any help would be appreciated.

It definitely sounds like your transformer is overloaded, especially if you are running two or more locomotives in a lash-up. The Z-1000 is rated for about 100 watts and 5amps, which would be ideal for a single locomotive (diesel or steam, with smoke and sound) with power to spare for a few accessories or illuminated cars. Higher speeds (and pulling a train) increase the amperage draw, so my guess is the combination of the lash up and speed are too much for the transformer to handle.
Given the size and complexity of your layout (you mentioned three loops and switches) and your desire to run lash-ups, I would recommend a power supply rated for at least 150 watts or more, such as Lionel's 180w powerhouse brick. Most operators opt to upgrade to a MTH Z4000 or Lionel ZW-C or ZW-L, but this isn't necessary. Older postwar transformers (such as the KW or ZW) will also work, just as long as you install a fast-acting fuse and/or transient voltage suppressor between the transformer and the TIU to protect the electronics.
You can also try running the switches and/or each independent loop off of its own power supply to provide as much power as possible to running one train.

Like John said.
You need more POWER!
Any of the suggested power supplies would be a huge improvement.
