CAMTECH/E/14-15/Colour Code – OHE Mast/1.0 1
Guideline for Standardization of Colour Code Scheme Feb, 2016
on OHE Mast
INTRODUCTION
Colour coding is required on different
OHE mast having some special feature like rail
marking, implantation etc. There are many
methods of marking (colour coding) on critical
OHE mast which are being followed by Zonal
Railways.
With a view to standardize the same
CAMTECH, Gwalior proposed for
standardization of colour coding scheme on OHE
mast. While proposing this ACTM & the
practices being followed at different railways
have been effort.
In this pocket book the references are
given as an when they are required .This will be
helpful for Railways for adopting uniform colour
coding scheme for OHE mast for easy
identification/ indication for convenience of TrD
staff.
