Engine shed - Electrically driven door

[ARIA31]

This thread is to briefly describe the construction of a locomotive shed with an electrically operated door.

This engine shed is made of 2 parts:
a) a main building and
b) a door module.



My main motivation was the door construction!
So the main building is quite crude, I am not an artist like many on this forum ..... !!

This construction has just had the honor of an article in the web review:
MRH (Model Railroad Hobbyst) from August 2020



Normally it is in pdf and available for free but this article is in the paid part (Running extra).
So it's just $ 1.99. This review is mostly O, HO and N !! But there are articles which are very interesting.

The main element of this achievement is the motor block:



The following video shows the rolling shutter in operation.

Great idea and well executed.

I like the end shot from the loco running in.

Looks nice!

Have you considered adding limit switches?

 

[ARIA31]

Totally right. There are 2 end stops switches.
The shutter is sliding in 2 U rails placed on each side.
The switches are at the top and the bottom on one side.

.

This is a very simple control device with a DPDT control switch.

Nice! I have seen ones that flip the switch, and have a diode as I remember, so once it hits the limit, the motor will only run in the reverse direction. I assume your setup has a similar logic!

Thanks! Greg

I tried this solution with diodes but at the end I choose to use the following circuit



However despite very simple , I tested that before installation on the shed !!
