This is Danish Litra III - a change from Litra I - and Litra II - 3600 Hk - 16 cyl emd something - Litra III is a 20 cyl. becorce of a extra generator to make elecktrik heat in wagons - 1500v - 360 amp - so therefor 3900 hp - old timer nice to see - i have driven them under DSB ( Danish Railroad )
Theyre a wierd engine, and look very out of place on the Australian mainlines, but "Helga" certainly commands a degree of respect. It's just a shame that the company that now owns them doesnt treat them with the respect such a capable engine deserves.
Pretty normal for an MZ... Theyre usually pluming black as you pass them. There still isnt much on the NSW network that will pull like an MZ III though. Don't expect to see one this clean ever again though... Since Qube took over Independant Rail and it's assets, the MZ's just get worked into the ground and neglected until they break and are all covered in years worth of grime.
All diesel engines do that when they load and unload through a generator or alternator, the governor tries to maintain constant revs and when it's upset it drops power to the engine so it maintains the same revs and when the load is back to normal again the engines loses too much speed and the governor has to rev it up again, same thing happens when you make transition from series-parallel groups of two to series-parallel groups of three, it unloads or a sec and loads up again, during slipping it happens more frequently as the traction control cuts power unloading the alternator.
@@jamieharmer5654 G'day, To make this easy to describe, take a battery and get 6 motors, for each of the motors connect the positive from the battery to the positive terminal of each motor, then connect the negative from the battery to the negative terminal to each motor, doing this to all 6 motors makes it a parallel connection, now for series-parallel it is similar except you get the positive from the battery and connect it to the positive terminal on the 1st motor, however for the negative terminal of the 1st motor you connect that to the positive terminal to the 2nd motor and do the same on the 3rd motor then on the negative terminal of the 3rd motor you connect that to the negative on the battery and that is a series connection, then you do the same to the remaining motors, 4, 5 and 6 then connect that to the battery and here we have two groups of series which makes a series-parallel connection, you can also get 3 groups of series by having the motors as 1-2 in series, 3-4 in series and 5-6 in series with the 3 groups in parallel. The advantage of series-parallel for DC powered locomotives is that the output was 2200 amps from the main generator and for starting trains you want pulling power and not speed, so by connecting into series you divide the voltage by the number of motors that are in series, this allows you to have the locomotive in a higher throttle setting to get high amps to start the train without having too much voltage as voltage is speed and too much voltage will get you excessive wheelslip, once you get around 30km/h you make transition by changing the motors into parallel and increase the voltage to the motors for more speed.

I have to question the reality of importing of UK/european flat ground locos on australian rail it looks like they choke on the less than 5% let alone their capacity to haul anything up 10-25% grades.. looks Victoria has found the same problem in their use is either trying to flog their stock to SA/NSW/QLD rail

Mind you that the Mz’s are new- *in Australia* in actuality the locomotives were like 40 years old before being sold to Australia
The 2nd video of the MZ, looked like the late Rob Fry on the right side of the cab.
Interestingly the backup locos behind the RL were good old first generation Victorian Railways T, B & S class locos!
1437 was blowing a fare bit of smoke in that first scene up the hill.
it had oil up in the exhaust manifolds, from light loading,powerpack change. it cleared up after a while.

RL301 looked like it was coughing
I suspect the RL is having turbocharger problems. I could be wrong though.

The RL liked to Rev down, Blow a puff of black smoke and rev up again. That doesn't seem right.
I think it cuts power when wheelslip is detected, the black smoke is from the engine governor loading up again.
@@turbonutterbastard69 it maybe wheelslip, but that is very aggressive. it will kill the overrun clutch on the turbo in a short time.
@@rearspeaker6364 The RLs have been in service for 13 years now, and they seem to be going along nicely with not too many issues, so.......

Rl class, a face only a mother could love
lol - design budget was $250 AUD for that loco !
why don't they use an electric locomotive since there are overhead wires. So much exhaust pollution coming out out that thing!
Often because other parts of the journey are off the wire. It’s simpler to run the diesels through rather than keep loco changing.
That RL dose not sound healthy
It was on trail so they didn't really care
