Also fitted is the close coupling system and buckeye coupler.
L.N.E.R. BUFFER BEAM
Cut the buffer beam shorter to the outer marker lines on the back of the buffer beam.
Using a razor saw cut the buffer beam from the end of the carriage. Fit the new one in its place.
Push the buffer heads fully home into the buffer stocks to represent retracted buffers.

Bachmann
LNER Thompson Corridor Connection.
Produced between 1991 - 2004
NOT USED
Remove any flash and file away any imperfections from the top of the resin corridor connection.
Insert some packing of plasticard (15-20th) vertically on the outer edges of the corridor connection
Colour the resin corridor connection with a black permanent marker. If paint is used DO NOT get any paint inside the aperture as this is a close fit for the end plate.
Place the spring over the spigot at the back of the end plate and pass the spigot through the hole in the centre of the corridor connection.
Push the fixing washer on to the spigot to hold the end plate in place.
Allow about 0.6mm of float. Adjust the position of the fixing washer to set the end plate with an equal distance all round the corridor connection. Ensure the end plate moves smoothly in and out within the aperture of the corridor connection.

ASSEMBLING THE CORRIDOR CONNECTION
Following the basic instructions the floor of the carriage has been cut out and the coupling base plate inserted level with the bottom of the chassis pan.
The coupling pocket has optionally been boxed by inserting a 1mm shim from the spru.
The shim is glued into place with a piece of 20th plasticard allowing the use of Roco couplers.
The similar Hornby NEM couplers are 2mm too long.
A false floor has been put into the inside of the floor and the coupling base plate fixed to it.
This is normally only done if an error has been made cutting the section of floor out.
THE CLOSE COUPLING BASE PLATE
The completed underframe with the Keen Systems Buckeye coupler fitted.
New buffer beam fitted and the old corridor connection removed ready to receive the new one.
FITTING THE CORRIDOR CONNECTION
Remove the rubber corridor connection from the carriage and clean the the area of rubber.
Ensure the new corridor connection is pushed up to the top of the hole in the end of the carriage. Secure with a small amount of super glue.
