Over here the two BSP threads are referred to as:
BSPP parrallel
BSPT Tapered.
Without the bits and pieces in front of me, I am doing the hear say, rumour, and opinion thing, but I think the bogie axle thread is all UNS (without looking up a chart) and I think they are completely interchangeable with the Australian carrier (about the only bits that are, save the bearings)
So Michael, get your charts, guages, and an axle out, and have a look.
Give us the dia. and tpi, or the result
UNS at 1 1/4" is 14 tpi. Is that it?
I have looked and found a chart for BSPP,(and it makes more sense now) with a 14 tpi thread as you say Michael R, so kindly disregard the ANS reference.
Like Rob says, Chase the threads in a lathe.
