The "Transit" postmarks are made by the American company that also made the flag cancels. These were used for a short period of time to record when mail passed through a transit point. In this case Washington DC is a transit point between Forest Glen, MD to Atlanta, GA. These are avidly collected by machine cancel enthusiasts.
I can't figure out why there is a Due 1 cent marking on that postcard.
As far as the World's Fair cancel, this is a reuse of the cancel used for t he Saint Louis World 's Fair. These are somewhat scarce and desirable.

The "due 1 cent" marking is because at the time of posting it was not allowable to write on the back of a picture postcard in the US (you had to write only on the front of the card) and it was charged letter rate (2 cents at the time).
This clipped from some unknown source some years back. "Postcards with a divided back were permitted in the U.S. beginning on March 1, 1907. (Britain had already pioneered this in 1902.)"
Hope that helps
I'm curious about the 1c due on the card.

Webpaper and Roy,
Thank you for drilling down on that. I've been picking up some postcards lately and do remember hearing along the way that there were periods of time where "split back" cards were important to meet postal regs regarding address placement etc.
We see one here in action.
When it comes to post marks, I understand that R P O is Railway Post Office, but this is 1 I have never seen TRANSIT?
Also I have never seen a DUE 1 Cent on a post card?
And 1 pot marked World's Fair Portland, Oregon1905?
