Oright, so today a mate & myself went to fix the blown fuse on Z.74, which we blew by trying to draw too much power on the party tram. Of course, with the tram being at the gasworks yard, we had to try and be as autonomous as possible for the repair job.
We dug out the 12V circuit (which appears to be a Bendigo-addition to the tram) almost all the way to the 24V-12V converter before we found the fuse. The 1st fuse was fine. The main 12V fuse was fine too. But no volts were getting through...
After a bit of testing, we discovered the problem: it wasn't the fuse. It was the freaking fuse holder!
Basically, we melted it a bit, and covered the fuse contact, insulating it.
We did a quick Jaycar trip, but they were closed, as was expected, so no replacement fuse holder. So we ended up taking the Z to the main depot for a bit of re-wiring, and for a replacement circuit breaker instead. And we failed the 'spaceship test'; we did not have a soldering iron, or power for said iron, or breaker, etc. We did not pass the full autonomy test, which in the situation of a spacecraft, equals completely screwed, or dead. So fail.
Got track permission, then headed out of the gasworks. I was warned the tram slips in the wet (Autumn day with lots of leaves on the track plus sporadic rain), and even with that warning, I had no idea what I was getting myself into. That Z car slipped all over the place something horrid! The speedometer was more or less useless, and bouncing up and down if I touched the pedals - walking pace is about 5kph, not 20... and on top of this, trying to keep safe, mobile, and non-hazardous to traffic. But I managed somehow.
It was very scary how easily 20tons of aweseome can be out of your control if you misstep.
The sand helped, but the auto-skid detection was not reliable, so I was on the sand button a lot. Very much a lesson on how to take things dead easy.
Got to the depot, ran straight in with the panto up (Gotta love that...), and pulled up next to a hanging 240V socket for the soldering iron. Rigged in a new breaker, soldered up the connectors good, heatshrinked the lot, then it was time to go - half an hour before power-down time. We took off, I went around the depot curves at about 5kph (which felt fast, given the braking conditions), and off we went. The brakes kept making the wheels slide, which was not helpful at the triangle junction (mandatory stop), and very slowly got moving onto the main road. I ended up using rolling resistance for braking where possible, so as to leave the braking alone with a tap at slow, and got it back to the gasworks nice and safe. Definitely the most interesting driving lesson I've had to date!
Interestingly enough, driving up Thunder St. hill was the easy part of the drive... on massive amounts of sand.
Oh, and when we handed in the tram keys afterwards, the service driver mentioned the W class in service was just as bad, skidding out in 1st notch, and picking up speed on braking...
Definitely a learning experience.

Panto upgrade.
As of Thursday 17th April, 2008, we have a fully pantograph compatible tram network, with depot access.
FKN W00T!
No more worrying about breaking a very expensive piece of tramway equipment (that also doubled as an electrical hazard), no more spearing in & out of the shed with a wheely-pole, just pop the panto up & go. I love it =D
Incidentally, this makes me one of the last drivers to have speared a panto tram for depot operations (the scrubber driver/s would most certainly be the last), and I got to help 'test' the shed arrangement with a bit of shunting (to get a visual on panto clearance/geek pron). Bloody powered over the insulator on road 1, heard the thrown arc, but didn't feel the acceleration jerk that a pole tram does. Makes a difference, saves wear on the insulator too, as the panto pan isn't insulated for as long a distance as a trolley pole is, the arc isn't drawn as far or as long.
Apparently made for good viewing, everyone got a good laugh, so that was alright then =)
Next day (being beer o'clock), dropped in after work to say boo and shoot the shit (so to speak), and there was a bit of drama. The double-bladed spring loaded points on Bridge St had broken, the linkage between the 2 blades had snapped, which meant that one blade was completely unsprung... And the poor driver had gone over it with 2 conflicting blade directions. Stayed on the track, but technically a derailment. So at the end of a Friday, no less, they had to find a few tramways guys to do some very urgent welding, and they had to be completely sober (rail safety). On a friday night. Nice timing!
Fortunately, it got fixed, and I learned a few things about how the points mech works. Or doesn't. Hmm, prolly both.
Anyway, this one is for you, Myrtone, you impudent nit. You're not always right, it's not always a matter of cost, and yes, double-bladed points can be a complete pain. So STFU about bladed frog points - or come up with a fail-proof design that will allow reverse running.
FKN W00T!

Party tram
The party tram was about a month ago now, can't believe I forgot to write about it.
Went pretty smoothly once we got started; before that it was chaos! Set-up the auxilary equipment, such as stereo, compy to run sound, etc, had it going pretty well... then it died. Turned out the 12V cigarette socket had a lower fuse than we were pulling, so that went. So we grabbed a spare socket, hooked a 25A breaker to it (a 300W inverter would pull 25A), and then had to make the wiring to hook it all together.
By that stage, I was stressing, as I was supposed to pick everyone up at 5, everyone at the tram stop ended up catching an incoming tram, then we headed out. Again. Got to Pall Mall... and the road was blocked. The tram line was only HALF blocked, they had a bike race on in town (thanks for the notice guys...) and the witches' hats were on the running rail, not the edge of the lane. So we made them move the hats so we could get through. Picked up the last of the peoples at the fountain about an hour late (they were going to be that late anyway, but grr...)
Cruised around for a bit, got some food, cruised some more, then handed the reigns over to my boss, who was kind enough to participate in the madness that is a LANaway-crowd event. By the end of the night, I was drunk, as was half the tram, our resident ninja had performed some pole dancing on the tram's handrails, and posed with the statues on the fountain in town.
And he was sober.
All in all, an aweseome night. Must do it again sometime! As soon as we find that fkn fuse we blew...

Trammin' off (the wire...)
" That's great, it starts with an earthquake,
birds and snakes, an aeroplane,
Lenny Bruce is not afraid..."
-REM, it's the end of the world (as we know it)
Ok, so today I had a charter tram, with a mate for his dad's 50th. Was heaps of fun, I got to laugh at idiots on the road, and hang out with some people I like, and I got to go for a spin of 369, the Adelaide H-car. Went without a hitch, didn't stack the panto into the shed (that's suck so fucking hard), got cleaned up, and then went to shunt 35 into the shed after everyone bar my mate had gone.
And I fucking forgot to change the pole to turn around.
So I speared on a carbon skid into the depot yard. FKN NICE WORK!
Well, it was pretty decent really, lost the tram lights, made a fuckload of noise, broke the retriever rope, but not the span wires fortunately, and in my panic killed the substation, which the restaurant tram needed to run. Ouchies!
But it wasn't quite the end of the world. Got the power back on in a few minutes; got the trolley pole down, and managed to untangle the loose rope from the overhead; and nothing was destroyed, apart from a snapped rope.
However, I don't think trams are ready to run wireless somehow.
Note to self: when it's dark out, make FUCKING SURE you really have turned the poles, double check. Maybe even triple check.
Oh well. Another oops! Hopefully I won't cop too much shit for it...

Well, the charter for my mate's dad went well, and had lots of fun. Oh, and Squiddy, I told you that I look awesome in that uniform!
