hello what is the height at the top of a double stack on a maxi I ?

 A quick google search yielded this. Divide by 220. |

Frank's diagram will get probably get you a pretty good estimate.
Keep in mind that the ride height of the AZL Maxi-I is likely slightly taller than the prototype (I don't know this for sure, but suspect it) and it also depends on if you are using normal height or hi-cube containers. I'm sure someone here can get you an actual measurement of a Maxi-I with the AZL containers. If I can find the time I'll try to.

thx for the answers
it gives me 27mm so with 35 or 37mm between two levels, I have enough room

I am planning an helix with 38mm between two levels, I will stay under 1.5% grade
I do not see what is a 0-5-0, do you mean a loco (I have never heard about this configuration)

"0-5-0" is a model railroading colloquialism referring to using one's hand to engage a piece of rolling stock. It is a play on the typical notation of driver configurations for steam locomotives, and refers to the 5 digits that most humans have on each hand. In the case of a helix, allowing for significant clearance to be able to grab a freight car or locomotive is generally not possible. But for other trackage like hidden tracks, staging yards, adjacent levels of a multi-level layout, etc, you want to leave space so that your hand/arm can reach beyond the front track in the case of a derailment or stopped loco. I've always used 4" as my absolute minimum vertical clearance above the tallest freight car. |

I am planning an helix with 38mm between two levels, I will stay under 1.5% grade As long as it is a single track and accessible from both the inside and outside of the circle, then it should be fine. I have had a 2-track helix (in N scale) which was fine for most things but reaching in to fix up after a derailment on one track it was tricky to avoid bumping the other train. More so, on the side of the helix that was next to the wall, as it was harder to access the outer track.
Plenty of folks build multi-track helixes in all scales, but the smaller the scale then the more important it is to maintain good access.

 Thank you. I see perfectly what you mean the helix will be with a double track, and accessible from the inside every where , and the outside for a part. Finaly the height will be 38mm, I can insert my fingers

Thank you. I see perfectly what you mean
