Maryborough West

Shunting 3


 

Here we see Queensland Railways locomotive 2472D being pushed back into the yard at Maryborough West as part of a shunting move by 1744D which is down at the other end of the train. 2472D was dead and by the look of it could have been on its way south to the workshops at Redbank in Brisbane.

The crew member you see in the cab is the shunter. He is actually sitting on the opposite side of the train to the driver back in 1744D so it's possible he was communicating with the driver via radio.

Queensland Railways has a rather confusing method of loco classification that probably makes a lot of sense to Queenslanders but is about as clear as mud to a simpleton like me who comes from south of the border. The 2470 class is a perfect example of the confused classification because it has exactly the same specs as three other classes of loco.

The roots of the 2470 class go back to the 1550 class which appeared in December 1970. That class proved to be very reliable and so more were ordered in to be delivered as the 2400 class - the only difference being some modular electrics.

In May 1979 delivery of a further batch commenced but these came with aluminium cabinet doors and and windscreen washers. Of course, such important improvements deserved a special classification and the 2450 class was born.

And in December 1980 the 2470 class began to appear. These locos had a lighter alternator, smaller fuel tanks and a re-designed cab that was safer for crew members. As I said earlier, all of the class had the same engine - the EMD 12-645E - and the same specifications. All locos in the class were built by Clyde Engineering.
