When I was a conductor, and the A/C was still running R32 and the J was still running R42 (I'm not that old 🥺... I got that job when I was like 25 😭) you used to have to walk between cars to get to the control panel on the other side.

Mind you, I had to do this rain or snow. And the trains had holes in the operating positions to the point where you could see outside. Going from Howard Beach to Broad Channel those old rickety tin cans was not fun.

There are hand holds between cars to hold on to to make sure you don't slip or fall. Keep three points on contact, and you'll be fine. Secure all your items to you.

But if you feel dizzy, don't do it.
