Look very good apart form the aspect ratio.
Are the real ones really wide or really low?
|
The real ones are quite wide (for a Japanese train). The length is too short
but I have something against Lego trains that go beyond 36 or so studs, they
always look too long to me so I always compress the ‘belly’ a bit.

The base is cleverly done though :)
Any idea how the real ones work as I’ve never seen 3 bogies stock before.
|
Afraid I don’t know. I built it all from photos and didn’t see any diagrams.
Many Japanese trains are BoBoBo as far as I know. Anyone else know?

Hello,
AFAIK, the BBB loco type is mainly used in Italy, Switzerland and... Japan :)
at the moment. The debate around CC or BBB loco types is a long lasting one
around railways engineers (BTW I’m not one of them). CC type is technically
simpler to build and eases the mass distribution on only two points.
Conversely, the BBB type is easier to run fast in curves because of the 3
short bogies. Possibly this is the reason why it is still in use in
mountained countries. But the mass distribution for BBB types is more
difficult to manage because you have three points, which sometimes requires
complex articulation systems for an optimal adherence.
In France a BBB type loco was produced in 1948 and ran until 1967. It was the
only one ans was named BBB 6002. This loco was produced for comparison with
the CCC 6001 type at the same time, it is the reason why there was no BBB
6001 :) . BTW I have tentatively produced the
french BBB
6002 loco some time ago. In Lego the problem of very short curves poses the
technical problem of shifting the middle bogie under the body of the loco, as you noticed
already.
You can find all the pictures

There are currently Bo-Bo-Bo (or B-B-B) locos running in France, the Chunnel
shuttle locos
