"1 Track" signs

[RMS Gigantic]

At every single-track railroad intersection (excepting perhaps the railroad crossings with crossbucks alone without lights), including in the upcoming Idaho DLC images, I keep seeing these "1 Track" signs below the railroad crossing crossbucks: [ external image ]

However, in real life and in Google Maps views, I've only seen such signs for 2 Tracks, 3 Tracks, 4 Tracks, etc, never for 1 Track. To supplement my point, here are Google street views of some real life single-track railroad crossing signs, including in real life jurisdictions within the game (especially the New Mexico example, though in many other cases the single-track crossings I remember from the game are 2 tracks or more in real life) showing the absence of any "1 Track" signs below their crossbucks:

Please pardon this report for being somewhat outside of the proper format, but this issue is so easily reproducible and so pervasive in positioning that I wouldn't know how to list every single occurrence of it.
