What are the various marks and annotations on a passenger coach?

June 22, 2019, 12:20 PM

There are a great many indications, marks, and annotations that can be found on the typical coach. The most prominent, of course, are the indications of the accommodations (class, whether sleeper or not, air-conditioned or not, etc.) along with the coach serial number that is on the side of the coach, above the windows. Small destination boards usually have the train termini or the name of the train on them; these are also above the windows, near the roof.

On the ends of the coach the classification code of the coach may be found (‘WGSCNY’, etc.) along with annotations of the base shed that is responsible for its maintenance (e.g., ‘BASE: JAT’). ‘CDO’ stands for ‘Coaching Depot’; a notation such as ‘CDO/MYS’ indicates that the rake belongs to the Coaching Depot at Mysore. Overhaul dates are also shown (‘IOH’ followed by a date for intermediate overhaul; and something like ‘R-9/03’ for a periodic overhaul date (the ‘R’ stands for ‘Return’).

Some other technical details and electrical data may also be found stencilled on at the ends. An annotation such as, e.g., ’70T’ refers to the 70-tonne rating for the couplers. On the ends, or near the ends on the sides of the coach, there are sometimes some annotations like ‘Fit for 110km/h’, ‘Not to exceed 75km/h’ or ‘For passenger train only‘, etc. These are usually restrictions noted based on the age and condition of the coach. (Similar restrictions can sometimes be seen on older locomotives as well.)

At the bottom left on the end of the coach, a small patch of yellow diagonal stripes indicates the coach has anti-telescopic construction. Larger patches of diagonal yellow stripes on the sides of the coach, above the last window indicate a general, unreserved second-class coach. Except that for EMUs, diagonal yellow (and red) stripes generally indicate first-class coaches!

SR and SCR coaches sometimes have notations such as ‘RAKE1’, ‘RAKE2’, or a specific train number or numbers stencilled on them. These very likely indicate that the rakes in question have been earmarked for specific trains.

A paint scheme indication is often seen. ‘MAROON’ is used when the coach is painted in the former IR standard rust-red colours. ‘VIBGYOR’ is used when the coach has the newer blue-on-blue livery, although it is not clear why the colours of the rainbow are mentioned here! Other annotations are used for other paint schemes. The date of the last repainting is also indicated.
