How do you incorporate somewhere to run in locos without a circle?

[BobDM]

I am still trying to figure out how to design a layout which includes an area to run in new locomotives and now I've discovered it's recommended that before attempting to run a loco on the layout it needs to be placed on a programming track.
To quote the DCC Decoder;

This is always a good idea as the lower power of the program track will not cause damage if the loco wiring is faulty.

Any ideas on how one incorporates a section in a layout where you can let the loco run itself in for the required time and not damage the loco because of too much power.

Sorry if this is a stupid question but I haven't seen any advice about it anywhere.

A DCC Programming track when feed from a dedicated Programming output will not be able to power a loco. It provides a low current output that allows programming to occur and prevents possible decoder failure in the event of incorrect installation.

Using a Rolling Road is an acceptable way to run in a loco on DC or DCC.

Thanks Brian. That's very useful.

Now all I need to do is find a Rolling Road supplier.

Some people just set up a separate circle of track for running in.

Keep a circle of settrack, radius 2 or above which you setup somewhere when you have a loco to run in. If you have a large piece of furniture behind which you could hide the circle on a piece of ply or MDF you don't even have to set up the track when needed.

Hi
In OO try Hornby or DCC Concepts. In N DCC Concepts are examples

I use a rolling road and a loco length of fixed track. These serve dual purposes each of programming and running by way of a pair of DPDT switches. One switch selects Prog - Off - Run and the other selects Fixed - Off - Rolling Road. The definite Off is to give dead tracks when not in use and also to provide a clear break before make twixt the Prog and Main power bus.
Running in ideally should be done in both directions at varying speeds and if using a circle by reversing the loco physically on track. This will load the motor-gear train in both directions and also load the running gear side to side.
