1995 stock is currently used on London Underground's Nothern Line. This model depicts the uncoupling non-driving motor cars which run in the centre of the train. It includes the body, chassis, and parts for two unpowered bogies.
See the Train Formation Diagram
for the correct arrangement of cars and recommended position of power bogies. For a shorter four car train I suggest omitting the two UNDMs.
Suitable wheels and bearings for the bogies are available from Parkside Dundas
PN66 5.1mm diameter metal wheels (pack of two)
PN67 5.1mm diameter metal wheels (pack of twenty)
PN51 Brass bearing cups (pack of twenty)
