The PS/2 coupler will certainly open on a PS/1 locomotive, they're designed to open on around 6 volts from the PS/2 board! I suspect they've decided that the PS/1 board can support the extra current and dropped the higher resistance PS/1 coupler from the product line. I have a bunch of them, they're handy because they still work for TMCC applications, the PS/2 couplers take out the R2LC triac if you use those.
