If you neglect animals in zoo, you could face legal action from animal activists. However, you neglect vintage and valuable locos in Railway Museum, nobody can touch you. (Although Rail fans may curse you, it does not make any dent.)
Mysore Railway Museum is a classic example of such neglect of vintage locos. The gate keeper will charge you an entrance fee plus camera fee, never issue receipt for camera fee and will not return the change, either. The sweeper will swap the dust towards rails. She has managed to conceal axel box of one (loco) tender so far.
Maharaja's saloon is so much full of dust that even a stray dog won't care to sleep there. I feel sorry for these locos and other displays.
The coach behind it, has had all fans lying on floor. Due for vanishing?????
W.G. Bagnall #1625 was made in 1900 for Khushalgarh - Kohat - Thal Railway which was a military frontier line. The loco was subsequently transferred to NWR. It operated at Timber Depot in Marala and was transferred later to Dhilwan Creosoting plant. This 2'-6" gauge loco is configured as 2-4-2ST.
