Not to turn this into a PRR thread... but....
It is interesting that for the 2-8-2 electric PRR went with L5, and the 4-6-4 they went with the P5
It seems like they were saving _1 through _4 on each class for iterations of steam classes. After the K4, maybe they figured they only needed 4 tries to arrive at their perfect engine for each wheel arrangement.
