The Bachmann F7 cog is a part that seems to be weak and continually breaks when it is it's original plastic form. This is because they force the axles onto the cog and split them.
This is a replacement cog so it stops it from that annoying clicking in the gears due to it.
Note: needs to be reduced by 10% of it's original downloaded size.
