What'd I do today? I thought more about transient suppressor diodes, these widgets:

I installed one yesterday across the posts on the Z 1000 power brick to protect against voltage spikes harming electronics. But shouldn't it be IN the locomotive immediately down-circuit from the $$ electronics we are trying to protect? So I looked under the hood of a PS3 SW1500 and wa la: the power and ground leads from the pickups and truck-frames are wire-nutted to the circuit board power leads. Easy-peasy: I just added a protector diode between  the two wire nuts:

       

       

BTW, a tip: if you need to remove the cab/hood from an MTH SW1500 removing the truck frames gives access to the front two cab screws so as to not scratch the paint on the truck frame. Don't ask me how I learned this 

I'd like to see this reposted maybe in MTH DCS PS2/PS3 to see what the experts say. It looks like a sound idea but I don't think most of those guys follow the What did you do on your layout today.
