Some months ago I posted my Power Functions High Speed Train with automatic doors. Although the door opening technique was novel, it wasn't very realistic and the construction didn't allow for train interior.
So I set out to make an even better door opening mechanism and this is the result:
Did you notice the retracting stairs and the lights flashing when the doors were closing?
Below are all the details about the train, see all the pictures in my Brickshelf folder.
The train makes use of Power Functions to control the following features:
- Train speed (adjustable)
- 3 front lights and light in the driver's cabin (adjustable)
- Sliding doors, retracting stairs and lights (on/off)
- Interior light in cabin (on/off)
The train front is mostly SNOT and has three working PF head lights. I thought I might as well use the last light for interior light in the driver's cabin. See this picture for a cut away view of the consruction of the front.
The mechanism for the sliding doors is hidden below the center car allowing for full interior. It uses the 9V micro motor, some gearing and liftarms. The lights above the doors use an old 9V light and shine constantly when the doors open and flash when the doors close. The retracting stairs... well, see the video and the pictures, it's pretty hard to explain.
Well, I had one IR channel left, so I added some interior light in one of the cabins:
One car is stuffed with Power Functions gear: 1 rechargeable battery box, 2 infrared receivers, 3 PF light cables (= 6 lights), 2 PF->9V cables and 3 9V cables.
The other one has a standard passenger train interior.
I think that was it. I really look forward to your comments.
