New locomotives

 
  Piecost Station Staff

The new Locos have been in testing for some time now, and I am wondering as to how they are holding up to the tasks at hand?

Are they showing any problems or is it all plain sailing for them?

How much longer will the testing continue before they are signed off and commence proper service?

Thanking you in advance.

This came up on Tasrail's facebook page last week:

On Wednesday 12th March, two of our new TRs will be entering the big wide world of revenue services as a part of the testing and commissioning process.
The TR’s will be shifted on to different services over this period including the Log train. Stay tuned to see how our newbies fare!

Could anyone tell me whether the TRs are running regularly on any particular train and is it too early to tell if there are any time table improvements.

Impressive looking train out of Hobart this evening with a trio of TRs leading a modest consist. Didn't notice how many new flat wagons were in the makeup.

Is a trio of TR's hauling a modest load an implication that the load hauling capacity of the TR's is no better than older locomotives?

I think the aim is long term reliability and economy over the older locos, rather than any radical increases in hauling capacity. Remember, the TR's are relatively small locomotives, considerably less powerful than the 'ZA's/'ZB's when they were new, but with modern traction control that would allow them to at least match the big EE's original haulage capacity, despite the smaller engine output.

Eventually when the state network's track gets sufficient capability, the next loco acquisition after the TR's (hopefully not after another almost 40 year wait!!) may, through better weight allowances, finally introduce some contemporary loco horsepower to the state. Baby steps first though. At least we finally have NEW locos, regardless of how small they are.

When one considers the size of the TR's c. 2200hp vs the mainland narrow gauge standard of c. 3300hp, it pretty much is a repeat of the early Tas experience of 660hp / 800hp 'X's & 'Y's vs mainland power rating around 1500 - 1800hp at the same time.

Train 636 just came through Devonport with TR9/TR7/TR3 hauling 41 loaded wagons.  As she headed west, she climbed out of the old Devonport yard without any effort and a lot less noise then the DQ's.  Nice to see a 41 wagon train again, been a while since I have seen a fully loaded one this long.  Also the rake of new cement hoppers brought into Devonport earlier are now on the cement train.  The old hoppers are now sitting on the first road in Devonport awaiting probably their final trip back to East Tamar.

Can anyone throw some light on the newer delivered TR's having baffles on the hand rails??

If they are to stop air flow, I would have thought better air flow would be a good thing....

Probably something they discovered a need for after noise testing.   There is probably a regulation guiding how much noise is allowed outside a certain distance from the loco and they help meet it.

A lot of newer mainland locos have some sort of shielding for the same reason.

About the only noise from TRs is the Horns. Plenty of irate members of the public now they are out and about in the early hours of the morning.

They make more noise under dynamic braking than in full power up a grade. Is this what the deflectors are for?

If the locos themselves were noisier, maybe the horns wouldn't need to be so unbelievably loud. Never have I experienced a loco horn physically vibrate my car, as I drove adjacent to it a house block away!

Experienced a touch of schadenfreude watching a pedestrian on the bike track adjacent to the track at Berriedale, desperately clamping their hands to their ears as TR's on Train 35 blasted their horns crossing Berriedale Rd. crossing! The poor unfortunate wouldn't have even heard the train coming until the horns blew and probably needed a change of underwear with the shock!

At least one wouldnt be taken by surprise by a DQ hauled train. Can hear them coming a mile off!

Well as TASRAIL wanted the Loco's to be quiet and the horn is a warning device, hence it should be loud, it appears the locos are working just fine!  

I did notice that TR07 and TR09 had 4 panals on the hand rails were TR03 only had 2.

I heard them at agfest going though oaks, I'm at the other side of the site AND surrounded by old engines!

I just caught up with 3 TR's tonight, and well the word i would use for those horns is.....

EPIC!

Man they pack some punch...

Edit: First really still clear night for a while out my way tonight, my nearest crossing is Briggs Road Brighton. I am about 3km's away from that as the crow flies....and it sound like i am about to get a TR in the front room.

EPIC!

In Burnie last night and I saw three TR's being attached to a rake of ore wargons to head down the West Coast.  I saw TR6 and TR11 at each end of the set, but couldn't see the middle loco.

Other locomotive horns were barely perceptible when crossing over Hobblers Bridge Rd Level crossing from where I live. The TR's can wake you from a deep sleep, I would suggest Tasrail have had and will receive many complaints from the Suburbs surrounding East Tamar Junction about the excessive noise during what is called the silent or sleeping hours.

I have heard the new loco's horns quite clearly during the early hours of the morning, and I live in Summerhill, near Prospect.

After having a yack with staff from TasRail, the TR's horns are Australian standard. Horns before them aren't but can get away with it due to loco age. Also you can't hear locos hauling a train, not like the EE or EMD ones.

Do we know the specifics of any teething troubles associated with the roll out of the new locos?

Would probably be a RISSB Standard but this comes from a ROA document - Locomotives

13.11.3 PNEUMATIC HORN
13.11.3.1 The warning horns shall be pneumatically operated and shall have the following minimum features:
(a) Compliance with the performance requirements of Clause 13.3.1
(b) Five chime or equivalent
(c) Bi-directional
(d) Low noise horn feature Surprised:

(e) Valve operation shall be backward for the main signal and forward for the low noise facility.

From what I have heard, the main issues seem to be inter-operability glitches between the various electronic control packages. Nothing unusual there - most new locos these days seem to suffer teething troubles with the computer based electronic control packages.

Mechanically, all seems to be okay, although I heard (right or wrong) that TR05 was causing issues for a while by inexplicably losing all its coolant. Whether that is still happening or has been resolved, i don't know.

TR06 has made its way onto the cement train.  That should make the locals happy now that there is a TR with is horn blasting through Spreyton every hour or so!!!

Is there any need for higher HP?, areas where speed is sustainable? Forgive me I havent been to Tasmania yet.

Going on what BDA has said in other forums, what I have read online, and what now makes sense in my mind, having a 2200hp locomotive producing 2200hp all day is better than a 3000hp loco producing less then 3000hp most of the time.
