Perhaps Royal Cresent, with the leg of the R squared off to sit flat on the baseline?
If you click through the link I supplied above, and scroll down the page, the designer provides the answer (and the R in your sample is actually an alternate character, not a customization):
Royal Crescent is an all caps sans-serif based on Johnston, the font found on London’s subway stations. The uniform width is consistent throughout creating low contrast. There are slight variations, between several upper and lowercase characters which can be used interchangeably.
