You will also have to modify the 12v conductor rails to be able to
attach them to 9v track. They have protrusions on the underside which
interfere with the studs on the 9v ties (remember, 9v track has half the
tie spacing that grey era 12v track has, and four times the tie spacing
that blue era 12v track has).
There are 12v contact pin blocks which connect to the old 4.5v motors
(which were also available in the blue era with 12v motors for 12v
trains). It may be possible to use these contacts, though my attempts
weren't too successful.
