Question; is it possible to fit a stay alive to DC locomotives on a DC layout? 
There is an obvious problem when the locomotive is asked to change direction.  I have seen devices being advertise on eBay.  Thanks

So if you use a section switch to turn off a loco in motion (and I know many that do), it will keep running....................................

Apart from the obvious shortcomings of loss of control as mentioned above - No, there is no way to usefully add a stay alive for DC use.

The better option is to make sure that the trackwork is good!

Also wheels and pick-up paths on the wheels need to be well-maintained.
Many locos that come to me for service/repair all too often need only to have their wheels cleaned, but many owners only clean the track to wheel contact area [the tread], ignoring the flanges. They also miss cleaning the back of the wheel which is wiped by the pick-up. They are over-lubricated as well, again permeating onto the wheels.
So, cleanliness and well-laid track should reduce the need for any further mods to maintain progress on analogue or DCC.
