I have run a wire from each car to the adjacent cars that way every car has two or three pickups to eliminate blinking as Brewman 1973 suggested from an OGR article.
I did this 30 plus years ago. The small flexible wires are connected with wire nuts inside the car and the Lionel 2400 series cars roofs are easy to remove. I drilled small holes in the car bulkheads but one can drill holes in the car bottoms for the wires.
I leave the 3 or 4 car strings together and grab the cars ends, two car per hand to move from layout to train shelves or vice-versa.
Easier, cheaper and quicker than adding a second pickup on each car.
