I saw RD402 on a work train on the shuttle in Times Square a couple of days ago. I got a close look at it since it on the platform. The interior still has advertisements from when it ran in service as #8956. It still has a nice shiny yellow/black exterior, but I did notice something weird near the center door. There is a fuel cap recessed into the side of the body, around floor level (of the platform), and it is stenciled 'Diesel Fuel Only'. Does anyone have any idea what this would be for?
