Octrainber 2022: Atg-1 deicing with a jet engine

[XG BC]

It is that time of the year again so lets start with my topic for this years octrainber. I had a more difficult time to find a prototype this year than the year before as the topic is very different and special. but ultimately i found one: a locomotive that has been converted to a de icing machine using a JET ENGINE from a soviet mig 17.

here is a picture of this loco before the conversion (not exactly but one of her sisters)

and here is it currently:

I guarantee that someone, somewhere, tried to either barbecue, roast marshmallows, or light a cigarette with this….

"In Soviet Russia, marshmallows roast you."

misspelled "roast" as "toast". Fixed now.

Never mind that. Just let the train brake off and give it the beans. Whoosh!!!! 

@XG BC That’s a great prototype. I’m looking forward to seeing your progress. When you mentioned jet engines in the other thread I thought I knew what you were going to choose, but I guessed wrong.

Strange design. What are they deicing with the nozzle not appearing to be tiltable? Great choice for your build. Can't wait to see it. Will you use a model aircraft turbine engine to propel it too?

Well, I believe it is, as judged from the two hydraulic cylinders attached to the frame and the jet engine, isn't it?

If so, this thing could also be used for weed torching - hmm maybe not, wooden sleepers may then suffer as well   

Best,
Thorsten

Good eyes. I missed the hydraulic cylinders at the bottom of the nozzle for tilting it.

I do recall seeing a number of steel sleepers on branch lines when I lived in Deutschland. Or for use with concrete sleepers. They shouldn't melt or catch fire. It would definitely work well on the weeds. Probably faster than when I torched my driveway pad.

it didnt have the thrust nozzle so not that much thrust was produced by the engine. but would have been quite the spectacle to see it running for shure. what did you think i was going to choose? just curious.

no. would make for quite the spectacle though. the model will be all digital.

I thought you were going to make the jet-powered Budd railcar.

[XG BC]

aah ok. that is a good one too.

[XG BC]

now i have started the build. the issue is that this one is a three axle locomotive with larger spaces between the wheels than are acceptable for r40 curves. i have several options now:

variant 1: simply say i dont care it wont go around r40 (not happy with this i want to make this work)

variant 2: making blind drivers of some sort to make it go around r40 (not bad especially for detailing as you dont have to make clearance for swiveling)

variant 3: using the same setup my vossloh g6 uses with a turntable (bad as this uses a lot of space)

variant 4: using a ball joint for the swiveling (good as less space is used but bad as you have to account for the swiveling motion and make room for that)

i am currently split between variants 2 and 4. i have thought about making the middle axle be able to shift side to side but decided against this as it would make for an incredibly difficult job getting the details in (model will be 6-wide as always)

[brummer]

Why not version 1 with side moving middle axle ?

[Hod Carrier]

I went for Option 2 for the power bogies on my CIE CC1 loco, and it works OK(ish) on R40s. It's actually a technique I first saw used by @dtomsen. Your loco should be fine as it looks like it's got a wheelbase 2 studs less than my loco plus, as you say, it makes detailing easier.

the issue with that is that you can pretty much forget about good detailing as the model will be 6-wide so there isnt much space for a side moving axle.

[XG BC]

i settled with option 2 as a swiveling part would have made it more annoying to add details. here is my progress so far. the loco isnt too complex as far as details on the undercarridge go. just a couple of leaf springs and other bits like a preassure tank and ladders.

model will be powered by cirquitcubes. it will be a digital model for now but i wanted to leave the option for motorization there. it is just a couple of bevel gears. quite standart drivetrain driving all 3 axles

[XG BC]

further progress: basically finished with the undercarridge and now starting on the body (the non modified version)

I'm in awe. Both at the Soviets* for creating the prototype and at you for finding & choosing it.  This promises to be amazing.

*Re Soviet, um, "ingenuity."  Many decades ago, during one of the 5-year plans when quotas were being handed out to all kinds of concerns, such as factories, farms, department stores, and so on, a certain chandelier factory was given its first quota.

The factory happily complied, and churned out the entire years' quota in a matter of weeks (or perhaps days).  The fixtures were manufactured in lead, as the quota had been set by weight.

[XG BC]

this is an east german loco of the former gdr so idk if the soviets built it or germans did. there are examples of soviet broad gauge wagons with similar turbines on them though.

[XG BC]

next step

the locomotive has a window each on the front and back side of the cab. the door handles are made just like on my e69 using minifig hands. the cirquit cubes just sits loosely in the cab, the main windows of the cab will be attached on top of it so that you can take out the battery cube for charging and to turn it on/off.

[XG BC]

moving on. this time i did the hoods. the ends of the hoods are at a slight angle which i made through the use of hinge bricks. the vents are done through a snot construction, 90% of the hoods is snotted. the upper light was the most dificult one to build as there wasnt any space due to the use of the hinge bricks. it is made by pushing a 1x2 panel into the top part of the hood. i also added a second motor so that the model would have a little more power (i dont know how much power a cirquitcubes motor has but i had space for a second one).

Wow!! That's coming along very nicely. I like how you've got the slope of the bonnet ends.

You do know that you have until the end of October to finish? At this rate you'll be finished by the end of next week. 

[XG BC]

yes but i have things like my final year of school to do. yea i am too fast but others are too. go to the german doctor brick forum and see

[Hod Carrier]

That's fair enough. I tend to be a bit slower because I know that I will spend a lot of time fiddling about making sure that I try and get all the details right, so I have to be organised when there's a competition deadline coming. So I'm pushing myself hard with this design to make sure I don't run into any problems later.

[XG BC]

fiddling around with details is another why i wanted to get going quickly so that i can have time to do it.
