[MOC] Baureihe 70.0

[Thomas Waagenaar]

Hello everyone!

I would like to present my second locomotive, a Baureihe 70.0, and again in the Bavarian colours.
The next locomotive I'll make will have a different colour scheme, I promise! (It'll be the exact same but dark blue instead...)

Just like my previous locomotive, this one is powered by a circuit cube and 2 of their small motors. 
They are geared in a 1:2.25 ratio in the smallest possible space I could manage. Using an 12 > 8/12 > 8 gearing I was able to fit this
inside the same space as two 2x3 bricks. This results in the locomotive having an accurate scale speed compared to the prototype!

It has fully functioning front and rear lights, and the wheels and rods are 3D printed to be functional and accurate to the real thing too!

The next task is to design some passenger wagons to go with it! And ofcourse to finish my train station. Just waiting on the last parts, as per usual, haha

Feedback and comments are welcome! Always hoping to improve my builds whenever possible!

This is another lovely model!
Do you have a video? It would be most interesting to see which speed you do achieve with your drivetrain solution.
Also, I'd love to learn about the internal design of that approx. 5-wide boiler - I'm building one at the moment myself and it would be interesting to see your approach.

The valve gear looks great!

Well, if you do insist...
I notice that, unfortunately, many models of German locomotives use wrong typefaces for the lettering, which is quite compromising to the realism of the model once you know it. The correct fonts are those of the "DIN 1451" family, and there's a lot of online sources to download them for free,

Thank you! I don't have any videos *yet*, I'll probably make some videos once the passenger consist is done! It's not super fast for Lego standards, but it's realistic to the scale and it can still pull something, so that's all that matters in the end! Haha

For the boiler, this is the technique that I'm using, sorta... I designed it with these parts, fully brick-built it so be properly functional...
...and then I ripped it out and 3D printed a single block that exactly matches it, so I could lift the boiler out in a single piece without risking anything falling off to service the way too many wires I stuffed in there because I can't solder for shit, hahaha

It's basically this pattern stacked along the entire boiler. The yellow plate on top is to carry a single long plate on top of it. So you can just make a T-part attached to the bottom snot bricks, build up to the yellow plate and just have that on either side. A long plate and some tiles will keep it together from that point onwards. Same for the side pieces that are attached to the blue round bricks! The bottom is empty because no one would see that bit anyways, and I can run cables through it.

Do note, that it actually is 4.6 studs wide, and not quite 5 studs even though it looks really close!



And regarding the letters, whyyyyy, I was living in ignorance so well! Haha, I actually used Bahnschrift (So DIN 1451) for the text and such, but I forgot to transfer it to the running numbers... Annoyingly, stickers for the next few projects have already been ordered and are laying next to me. So now is the dilemma, stick with this incorrect number font, or get them re-printed (Was pretty expensive, as I don't have the capabilities to do it at home myself sadly). I kinda hope I'll just forget about it again 😂

[Sven J]

Ah, thank you.
I've come up with a rather weird design for an exactly 5-w boiler, but have to try yet whether it's sturdy enough. I'll show it when I'm sure that it works.

That sounds interesting! I'd love to know a technique for a 5-wide boiler! I'll probably have a use for it in the future as well if it works!

Thank you! It'll be especially awesome once the consist behind it gets finished, haha

Well done! Love seeing some "Länderbahn" engines here!

[rjr]

Yet another great one, you keep posting one after another like there is nothing else!

[idlemarvel]

Another masterpiece. Well done.

Thank you! Honestly I love the 'lokalbahn' feel of these locomotives! And I definitely intend to stick with it in the future as well, though I've got 2 "medium sized" locomotives planned as my next 2 locomotives, but still trying to keep them within a "realistic" view as in that they would service the edges of the local lines, haha. They're a 2-8-0 and 4-6-0, bonus points if anyone manages to guess which ones ;)!

Thanks! To be honest, I design them online before I order the bricks, so usually I design faster than sellers sometimes ship bricks... And the previous posts, the 89.8 and the wagons were finished at roughly the same time, I just waited a bit before posting. I've actually finished my train station already too! But haven't made pictures yet, I intend to do that next week, so they'll likely get posted next weekend!

If only the S3/5 would be a branch line engine

I had been thinking about it, but she was too big, and sadly wouldn't really fit with the rest of my theme in size...

As such, my choices are Prussian for these, not quite as small and local anymore, but small enough that they'd not look too out of place compared to any of the big express locomotives 😅

Wow nice work @Thomas Waagenaar! Thanks for sharing!

[LEGO Train 12 Volts]

Beautiful new locomotive...still in a dark green livery! 

Impressive how the light wires are so thin and the lights so compact. 

[Elysiumfountain]

Beautiful creation! I love that there are lights :)

Yesss, the Green is slowly bankrupting me though... 😭

Got 2 small passenger wagons planned, made 2 versions, a more complex and detailed one that resulted in a price of 75 EUR/wagon... And a more simple one that's 40 EUR/wagon, now it's a matter of deciding how much I care about those specific details honestly... 😬

Thanks! Honestly the lights were a must for me, so I always try to give everything lights, buildings, vehicles and my passenger wagons will have some lights too!

Just a thought: if you can (maybe you have already,) plan things out so your part inventory for the 40 EUR version is as close as possible to the 75 EUR version. That way, you can build the 40 EUR version now so you have a train immediately at semi-reasonable cost, knowing that you can spend the extra 35 EUR or so to upgrade the coaches when you have the funds.

I've been thinking of it, but sadly not. One of the designs just goes with the flat sides of bricks, the other is SNOT with tiles. So other than the ends of the wagons, nothing really overlaps much in parts... :(

Honestly though, I'm probably going go to for the simpler version, because most of the details and eye-catchers aren't in the body anyways, they are in the roof and end platforms, which will stay the same regardless of which version I'm picking, haha

[L-Gauger]

Gotcha... well, at least the end hardware is the same. And presumably the frame/wheels too. That's still a fair bit of parts in common.

In that case, I think your instinct to go with the 40 EUR version is a good one. SNOT tile sides look great, but in my own models I've historically preferred bricks because the build is simpler, and adding a good-looking interior is easier as well.

Yeah, it's pretty much the "box" being different and the rest all the same, haha

And I intend to give them interior too now that I've got more space for it going the simpler route. They were always intended to have lights, so it'll be nice to have lights where you can actually see an interior, even if it's just super simple seating in the end!

[LEGO Train 12 Volts]

I'd definitely go for 40 EUR to get two carriages for the price of one... but I understand the hesitation, especially if deep down you feel like you're getting the right solution. 

I would love to see the cad designs of both if you have them.

Here is a little spoiler then, haha

I'll post more/better pics eventually once they're done in proper bricks!

The left is the SNOT way, but already thinned it out to ~65 EUR, I did substitute a specific Lego piece for a Bluebrixx one already too, because the Lego option would be 40ct/piece, and I would need 20 per wagon... 

As you can see, the difference between them isn't that huge in detail, but it definitely is large in price!
