Height of rust – addendum

Today I saw rake 2121-2124 from the top. The roof of each and every coach of the
12 coach rake has rusted. The roofs of a couple of coaches (especially
motorcoaches) had more rust than paint. Call it great quality!
Click here to see another specimen rusting before reaching Mumbai. I can see rust at at
least 9 places on the partly visible right hand side coach (which means
there will be more on the remaining part), and I can make out two on the LHS
coach.
