Mettupalayam-Ooty Passenger, leaving Coonoor, pushed uphill by a bio-diesel powered YDM-4 loco #6225, brought to Coonoor from the main-line metre-gauge routes in the plains. Hence you will notice that the locomotive is longer than the carriage!
As there are no centrally laid toothed rack-bars on the 19 Km stretch between Coonoor and Ooty, the maximum gradient is 1 in 23, i.e one foot rise/descent for every 23 feet of travel. Hence it a normal adhesion line allowing the use of this locomotive.
Only the specially built Swiss steam engines can operate on the 1 in 12.50 gradient rack and pinion route between Mettupalayam and Coonoor. So, this diesel engine replaces the steam engine at Coonoor for the run to Ooty.

u can run steam trains on bio diesel or veg oil or waster oil like diesels or old wood etc so in theory it should be possible to run a steamer cheaply?
plus steamers can last forever with just simple tools.

@rush2astha Burning anything releases pollution, idiot.

@tpvalley The thing is though, that carbon is trapped below ground. By burning it, it will take millions of years to go back, unlike biofuels, which simply recycle the carbon already in the atmosphere.
But steam engines have such a tiny part in carbon emissions its negligable. I'd rather see a coal fired steam engine be hauling this, but it is too expensive, unfortunatly.

Great Video, 5 Stars! Why is the loco at the rear?

stupid any fuel when burnt produces fumes

If u burn any hydrocarbon u produce pollution.
It is said that bio diesel is carbon neutral as u r only releasing the carbon that the plants absorbed back into atmosphere.
I suppose if u think hard enough u could say the same about coal as that comes from trees etc millions of years ago.

hmm...there are lots of people with this mis conception that bio diesel doesnot produce pollution..but actually the case is that bio diesel is at the end diesel, its a fuel which burns and makes smoke but the advantage is that bio diesel has 10% more oxygen content in it hence making the burning less polluting than normal diesel..
