Excellent set up :wow:! The attention to detail is superb :)9! You can always tell your mom, at least you didn't dig the tunnel through the kitchen,...or you did you? ;)! Maybe you just left the truck as evidence of the bigger plan :evilplan:!

Hi !

great story and great pictures.

I love the idea with the underground train and station, but I guess I will not have enough space to realize it....

With a 3% inclination you need 10 meter rail to get down to 30 cm under the ground and another 10 meter to get up again plus several meter for the underground station, my garden is far to small for that.......

Regards
Rainer

Hi Damo !

Quite easy.

Imagine a big triangle...

Each meter rail with an inclination/declination of 3 % gives you 3 cm loose or gain of height...

so 10 meter with 3cm/1m gives 30 cm difference in the height....that´s the minimal height you need for a playmo train.....

So you need 10 meter to get down to the station and another 10 meter to come up again....

Regards
Rainer

It's a gradient of about 1,72 degrees. Correct? My maths is a bit rusty.

Any steeper and the train won't run properly, right?

If I am not wrong the formula is angle = arctan(0,03), but if have no calculator here.......

Yes, 1,72 degrees is right!!!

I used calculated the sine and used the calculator to convert it to degrees. But as I said, haven't done this for many years and my calculator has no arctan button.
