The little engine that could climb a 20 degree hill

bartneck

I modified this little train to be able to get up 20 degree hills. The whole movie is filmed in 360 degrees, so spin the camera around and find the Unikitty.

Powerful little beast. I like the (not so) subliminal advertising of your books!

How are you achieving the climb?  It looks like the train accelerates greatly before hitting the ramp but it could just be conservation of the momentum of coming down the other side?

The power comes from three motors and two battery packs. To get over the steep humps the bogies need to be raised. And lots of fine tuning.

I always wondered if it'd be possible to do a cog railway. Obviously you could, but would it work?

@SumoLego is going to have a field day with this.

I thought the monorail system was a cog railway.

Oh you meant IRL. Yes there are real gear railways. There's a famous gear driven mountain railway (I'll have to google it).

I’d give @Paperballpark the benefit of the doubt and assume he has heard of real cog railways :) I like the idea of a LEGO one (that isn’t a monorail).

GeoTrax track is the same width as the Lego track in #7199. I never tried making a Lego locomotive to go on it, but I did make a few cars for the GeoTrax locomotives to drag around the last time I had the GeoTrax set up.

Actually, other than the super-boss lounge chair near the windows, clean houses make for boring observations.  Give me a good photo of a basement, LEGO room or garage - that's what makes me happy.

While Mt Washington has its charm, I think the Pike's Peak narrow gauge cog railway may be what you had in mind?
