APT prototype can concept study

[James Mathis]

I found an old hard drive with many of my train MOCs. Came across this abandoned design study for the cab of the British Rail APT prototype. I recall it was gray in real life. I was entertaining the SNOT of an interesting slope element that has studs on the slope section…and the complementary angle made with that of a SNOT cheese slope. It all seemed to fit rather nicely. Alas, I never built it with real bricks nor did I continue the MLCad project.

Here's the link to see an MLCad screenshot:

P.S.: I wonder what else I might find…re-discover.

Interesting idea. It also makes a nice shape for the old ICE.

Following the trials of the real APTs, BR sold the design to the Italians, and later we bought back the Pendolino.

Therefore, if you'd like to make your APT tilt, a mechanism like the one in my Pendolino might do!

It uses bevel gears. Each carriage is like a differential gear, tilting by the average of how much the two bogies are turning.

Mark,

Your bevel gear solution is quite clever. Nicely done!

To myself,

In the mix if your own gallery, it would seem you are lost and forgetful(old man). Seems you can't remember posting this APT Exp prototype before...

Tucked away in this obscur folder, a movie of the tilt in action:

Rest in piece Eric Brok, whose pioneering efforts in tilt and close spring couple inspired many a LEGO® train builder. I remember marveling and studying Eric's work for both his engineering and artistic prowess.

I wish links to his historic works preserved.

It's nice to reflect and be reminded of our collective and cooperative efforts, as well as seeing the amazing evolution and original designs that train builders output to this day.

I like this cab and it does look like the old APT to me. It is a pity it never came to anything in the UK as for a time it was looking like the way to go. Still glad that others managed to get it to work and we have them now anyway.
