It is a diesel hydraulic locomotive with the torque converter just forward of the cab, and with the final drive output flanges between the two fuel tank halves connected to cardan shafts thence to each axle. With axles mechanically coupled on each bogie, this would make it to be of B-BDH notation.

In transit from the builder's plant in Bangalore, awaiting being transferred at Dharmavaram (Anantapur), the division point between the Southern Rly and the South Central Rly, for onwards shipment to the north.

In transit from the builder's plant in Bangalore bound for RRVUN Suratgarh Super Thermal Power Station, Suratgarh (Ganganagar), Rajasthan

There is a Larsen & Toubro Ltd, Construction Division Cement Products factory at Chitheri, Tamil Nadu at km 3.
- What do they make here? Pre-stressed concrete sleepers and bridge beams? Or possibly tunnel lining segments?
The loco is most likely to be a Ventra diesel hydraulic locomotive. However, L&T also operate a similar SAN model type DL-220BG-FD at their Jharsuguda Engineering Works, Orissa. You would need to read the manufacturer's specification plate located inside the driver's cabin to be able to make a positive identification and check the builder's Serial Number.

@Ramesh - (The unit at Dalmiapuram (Kallakkudi Palanganatham) where Dalmia cement factory is, should be a BHEL-built diesel electric shunter -Bo- with about 260kW, but we do not know the serial number.)

Nope, this loco was despatched directly to NTPC-Talcher from DLW on 30/6/2002 with the works #468.

Good snap.

Was this loco with any of the IR sheds any day earlier?Looking at the classification WDG-3A(?) near the right buffer and the unusual road number T0008,looks like it was transferred to TSTPP from some shed.

Livery looks good.

Oh! these people are obsessed with the names "Chetak" and "Pushpak". Wonder how many locos have been carrying the same name tags!

Nice shot!!

Nice finish and working.
Is this a Bo-Bo arrangement or only the LH side (far side) wheels powered?
