Undercarrige of B&Ms - CoasterBuzz

Does anyone have pics of the undercarriges of B&Ms? I really want to see the anti-rollbacks and chain dogs because I have never seen anything under the trains. Thanks.

I would think it would be really hard to get a pic of the undercarriage, considering that unless you are a mechanic, you dont usually see the train unless its on the track.

I did find this pic though. Its not the undercarriage of the train, but its all the mechanical stuff under the track/train of medusa.

-Why a car if i could have a coaster train on wheels??

Yea, I've seen that picture. Hell, you can see that when you are heading to the switchbacks of B:DK. I wanna see the chaindog and stuff like that

You can see them on Iron Wolf when your on the exit ramp. But i don't have a picture, sorry

I doubt you could find a picture of it, just because of the style of the track. The spine would block it, so unless a train is in a maintenence shed, and you can see in it, you probably wouldn't see it. However, maybe on that patent site people are always linking to, there might be a diagram of it.

...somebody have that site in their favorites where they could find it?

I do! the search site: http://patft.uspto.gov/netahtml/search-adv.htm

the 2 B&M patents that i have found:

That second one I do not believe is a rollercoaster, but rather it is a coaster for placing beverages on. It was interesting to see that some one has come up with a coaster so that I can find my drink in the dark.

If you go on Nitro, as your going up the queue, you can see the chain dogs clatter against the anti rollback devices. The only thing i don't know is what do B&M's use to acualty grab on to the chain.

I have a several, very clear picture of X-Flight's undercarridge... do you want to see that?

I wouldn't say it's that hard to see. Here's the bottom of a Nitro train. If you look carefully you can see the chaindog and anti-rollback.

Is the spine hollow on that Nitro train, Jeff? Where does the chaindog retract to if its solid?

The chain dog does not make noise when a train is on the lift, except a few clicks engaging the chain at the bottom and possibly disengaging it at the top.

The chain dog is solid and does not move. The anti-rollback dog on many B&Ms (the ones I personally am familiar with) are located just to the left or right of the chain, and will move to constantly engage the anti-rollback device on the lift (hence the sound).

Some coasters have different placements of the anti rollbacs and chain dogs. For instance SUF doesn't have anti-rollback dogs or chain dogs on all cars, just a few positioned in different places on the train. Many B&M's share this characteristic (which is perfectly fine).

I doubt the spine would be solid. Can you imagine how heavy that would be?

And the chain dog does move. How else would it engage and disengage the chain? It needs to skip over links or it would "hang" on the chain until it could release.

I know the chain dogs on SUF, the Scorcher, and BTR are pretty dang immobile.
