Hump Day - Behind The Awkwardness

“This is a photo of my parents. We were taking family pictures around some trains and this was written all over them. We still have no idea why.”

    It means that car is particularly fertile.

  2. Switch says:

    A train can be sent to a hump yard, a hump yard rearranges train cars by rolling them into each other causing them to smack the couplings.

  3. Switch says:

    A hump yard causes trains to latch together when they pic up speed and smack into each other.

    Alas, it is not as much fun as it sounds.

    A hump, or hump yard, uses gravity to help sort cars. This is sometimes a little rough on the freight cars and their contents. Accordingly, cars with especially delicate contents are marked DO NOT HUMP, which tells the yard crew to set the car aside for special handling.

  5. FS says:

    It means don’t use a hump to sort the cars. More detail here.

  6. Mike says:

    It means that you aren’t supposed to push the car over a small hill and let it run into other cars to link together.

  7. John Miller says:

    Railroads use a yard of tracks with a hill at one end to make up trains by pushing the cars over the hill or as the call it, a hump, and then let gravity do the work as the cars roll down the hill on to different tracks to make up trains. The yards are called hump yards and some railcars are marked “Do Not Hump” if then cargo could be damaged by the humping process. Hope this helps answer the question as to the reason for marking the cars as such.
