Unlike other horns in the P5 family, there is no known shorthand for the P01235. The horn uses the new, low profile P-manifold also found on the P5a and all P5's after the mid-1970's.
The P01235 was developed in 1974 at the suggestion of Amtrak's Don Tead. The horn uses the large O bell in place of the #4 bell. Both bells play the same note (A), but the O bell is an octave lower. The horn was only used on Amtrak's two orders of large GE electrics, the E60CP's and E60CH's.
Factory tuning was: A major dominant 7th (A,C#,E,G,C#).
The P01235 was unique to the Amtrak E60's, and will presumably vanish when Amtrak
retires the last of them.
