Bachmann 31-452 ... 170301 South West Trains
	Bachmann's Class 170 models, again whilst not part of their super-detailed "Blue Riband" range, can be described as drop-dead gorgeous! In two car versions, as with South West Trains, the eight wheel flywheel drive is in one driving car. 170301 appeared in 2001, a second version, 31-452A, 170302 appeared in 2004.

Bachmann 31-460Z ... 171721 Southern
	In 2005 Bachmann produced a special limited edition version for Modelzone - a Southern 171. It appeared just in time for Christmas! The paintwork is again of very high quality, though the lighting on the cab fronts in incorrect for a late version 170/1. The dummy coupler on these models is a bit indeterminate so it was not changed for this model - the model coupling is neither an accurate representation of a BSI nor Dellner coupler!

Bachmann 31-460Y ... 171724 Southern
	After a delivery some 18 months later than originally publicised, in February 2009 Modelzone released a second version 31-460Y 171724, with lightly weathered underfloor equipment.
