1. Rd8 Rf4 2. Ke3 Ra4 (Only option is to try and get the pawn home) 3. Be7 a2
Tried pushing the pawn...
4. Be6+ Kh5 5. Bf7+ Kg4 6. Rg8+ Kh3 7. Be6+ Rg4
And it's game over from here

ADD: Ok! After some more study on this I can see you are definitely correct! If black tries to get the rook behind his pawn, he is certainly doomed. However knowing black is doomed by trying to push the pawn in this way...why shouldn't black instead hang the pawn to try and get an attack on one of the bishops?
1 Rd8 a2!

This is Philidor's position. I think white can force this position or one similar(Lolli position) even without the cooperative checks from black.

Edit: The position shown is a win for white... If it is a draw then it is before this posiiton.
I am not sure how white forces this but with the king on the edge of the board I think white may be able to force this position(or rotation) or a similar position like the lolli(or rotation).

how can 5...Rg4 if the black rook is on b4 and a white rook is on d4? I'm sure there is a misunderstanding somewhere... This solution is a "domination" of the black rook.

My mistake.
