think the siemens could do with the same exterior colour as the
CCL sets of black and a red stripe at the bottom?
and the interior flooring should have the same material as that
of the 237 set. It is unique and its like a 'sneek peek' to
the C751B's flooring design. I remember it to be the only
train which had a unique floor design in 1237 and 2237 and the
train used to have a very pleasant smell that all other Siemens did
not have.
