Shinkansen 800 Sakura (Tsubame) - WIP

Recommended Posts

Posted (edited)

This is my first MOC regarding trains.

I am a great fan of Japan and its great history of trains and last year I was lucky enough to visit the country. I was astonished seeing and traveling with some of them and especially with the shinkansens!

As a LEGO user, I tryied to recreate the Sakura 800 (Tsubame) and I would like your opinion regarding my creation. I tryied to built it as close as possible to its true scale, and the most difficult part was the curved nose. I have made a dummy model of both engines to test its funcionality, but the completed model of the engine is made using stud.io.

In order to adapt as much as details as I could to the nose, I made my model 7 stud wide, despite the dificulties that I faced. 

All comments will be much appriciated.

Below you can see my dummy train test run.

Update 02/05/20: I managed to complete the digital model, and I designed two types of the pantograph. The seccond one, I believe is closer to the original. Unfortunately, i wanted to built also the interior, but there is not enough space, so i am thinking of trying to see the outcome in 8 stud wide, although the length will become bigger.

I hope you like it!

Wow, it's impressive how the model is fast! :wub:

Thank you for your comment. 

As Shinkansens are some of the fastest trains in the planet, I wanted to incorporate this characteristic in my model, so for the moment there are two pf train motors, one in each end of the locomotive.

Hopefully the speed will remain after I complete the whole model by adding 4 extra wagons.

I would only add 2 (or maximum 3) extra wagons in order not to lose beauty in the shapes but to lower the weight of the moving masses.

My high-speed trains despite having only 4 modules are still elegant

Really nice creations. Both of them are very detailed and well recreated!

I have also thought of the lower weight issue, that might be a problem in the wagons. In the locomotives, I used the battery box to bypass it, and in the wagons i am thinking of using the Modified Brick, 2 x 6 x 2 Weight, in order to help a bit.

Of course, I will start by using two wagons, and depending on the resault, I will see if I could add some more.

edit: Ι would like to ask you if the magnets you used are strong enough to pull such weight.

With this configuration the standard buffers are sufficient, in addition you also have the engine in the tail locomotive which reduces the possibility of separation.
In the case of longer trains I had used a super magnetic disk between the standard magnets to increase the coupling capacities. Look in the central convoy that silver part between the locomotive and the service cart (not easy to see ...between the magnets), that is a super magnet :wink:

Thank you very much for your reply.

I strugled a lot to find out an easy way to couple my locomotives without using the standard buffers as I thought that they would be insufficient. In the end, I used some technic parts to achieve the best result.

What a great start. It looks like the windows on the prototype are closer together than your MOC, I think you have one window every 3 studs, maybe try it with one window ever two studs? Just be careful, you're likely to find yourself wanting wide radius curves (grin)

Thank you for your comments! I have also spotted the windows issue, and I will try to amend it! Regarding the curves, I am lucky enough and I have no problems as seen in the video in the fisrt post.

Ha ha, I said "wanting" not "needing" after I built my first long cars I was in deep want of large radius curves even though the train could handle R40's. Though As the train gets longer you might start experiencing drag, so maybe only build one or two cars at a time so you do not wind up with too much train for R40 curves

:laugh: I didn't notice. That's completly true, I sadly believe! I'm in search for some tracks just in case they are needed.

Also, I tried to use some gears to make it go faster, but I had no luck, as the torge is high enough, as it is the weight of the locomotive but the outcome is slow.

Following up my original post, I would like to inform you that I managed to complete in studio the whole train and I updated the photos on the main post. I created two types of the pantograph, and I ended up with the seccond version, after seeing closer pictures of the actual one. I also wanted to put some interior, but there is not enough space inside. I am thinking to design it at 8 stud wide, although each wagon will get to be longer, and I will probably experiment with it. I hope you like the outcome.

I saw your videos on YouTube! It's good to now have the background story. :laugh:

I love how you've done the doors! The vertical tile on either side is very effective.

For the nose, me personally I'd try to minimise the number of different curved bricks in use. You have a section where there's a new brick profile every stud, it can make it look a bit jagged.

But yes great work, it would be awesome to see a beautiful 800 series out there.

That's impressive! Quite the shape for a first train MOC but well done.

Thank you for your kind comments Beej.

Regarding the doors, I wanted to do something that made clear that there was a door, and that's how I came up with that idea. I'm glad you like it!

I also agree with the jagged section that you are referring and this what I try to overcome right now. Its very tricky to achieve something that looks appealing.

Interesting.  You could put motors in the middle wagon cars such as in the real shinkansen.  Also regarding curves, have fun, yes 3rd party stuff is always the best look and quality if you want to see the min curve of your train you may need to try some flex track bent to high radii this will show you how much speed may be affected and how many motors you will need if you bump up your radii.  But I notice you have a 3rd party double crossover so you may know the quality possible beyond flex track with no FDM 3d printed stuff.

Thank you for your comments! 

I am planning to have at least one motor in each wagon, depending on the total weight of the train, and how much speed I would be able to achieve.

All LEGO I use, are original and not third party for the moment. The double crossover used, is the 7996-1 set back from 2007!

I was only 5 back then. I remember it loosely but I should've known by the bad design.
