A few months ago I bought a Hornby tube spanner for Hornby trains, to undo the hex nuts on the drive wheels.
Today I needed to undo and refit the hex nuts on a Bachmann Mogul, and tried the Hornby spanner,
amazing it fitted, making the job a lot easier.
For the low price ($6 AU + p&p) of the spanner, it makes a hard job easier for us guys.
Will try it on other Bachmann locos and will advise.
