Another shot of WAG7 27512 Prayas from CNB. The entire overhead electricity transmission assembly is covered and only the Pantograph seems to be left with space to move. This has its advantage of lower dust and grime getting into the contacts but has the disadvantage of more complicated Maintenance. Perhaps the advantages win over the disadvantages - a reason the cover is still in place after all these years?. Bilaspur Station, July 2005. Alok Patel.
