Cave-Ins

Carved tracks on a section that caves in will appear on the ground where they land (destroying ramps they land on). Feature or bug?--Nimblewright 12:34, 4 December 2012 (UTC)

Minecart Tricks

Has anyone considered compiling a list of unusual things you can do with minecarts, like dwarven rollercoasters or traps?

Sure. Here are a few examples:

The Stupid Dwarf Trick using a perfectly agile soldier to create metal could be done using a cart moving back and forth on rollers.

A clock generator using a pressure plate and a minecart can be made with on-ticks at easily adjusted intervals. Simply put a roller at either end, or, even more simply, make a loop track with a pressure plate in the middle and adjacent rollers pushing outwards. While the rollers are powered, the minecart will continue to roll back and forth on the tracks and trigger the pressure plate again and again.

Dwarves can be flung across impassable chasms using carts; this is similar to the H.E.L.P.

Squad cars: Have a powered system to move your military quickly to the front entrance of your fortress. Give all your military hauling jobs, and have a series of carts hidden behind a bridge; the lever closes them in and opens the cars, then the squad moves at extremely high speeds to wherever the track takes them. This is horribly impractical, but very dwarvenly. Note that full speed rollers move carts about a tile every two ticks, which is much faster than most dwarves. It's an insane amount of work to get it to work, but it might be worth it? The Real Marauder 01:23, 22 May 2012 (UTC)

I support the Squad cars idea; we may not be able to mount actual beasts into battle, but now we have the next best thing (I have a delirious/delicious image on my mind right now I wish you could see). Also, how about carving tracks running straight from one end of your entrance corridor to the other, with a lava moat on the innermost part so you could fling magma-filled minecarts to run down invaders? It could use a bridge-based minecart gate as suggested by The Real Marauder above. (This assumes carts drop contents on collision, as suggested by Toady's 05/10/2012 entry.) --Seikatsukan 22:52, 6 June 2012 (UTC)

How about minecart "landing pods" that actually launch the soldiers out of the fort into the middle of the battlefield, splattering enemies while delivering the soldiers straight to the fun? Could this be done safely? -Billw

Bridges versus Hatches

It's been noted that retracting bridges can be used as track direction switching points, as well as the fact that bridges will fling minecarts if they happen to be in the way while the bridge is switching. Would hatch covers also work for this? If they do, they would have the advantages of being instantaneous (rather than a 100 tick delay) and non-disruptive to minecarts (since they don't flingify stuff). --Quietust 03:59, 17 June 2012 (UTC)

Hatches have close to the same friction as ground thus making a poor substitute for track.

Capacity

We could probably improve by listing a few (verified) capacities of minecarts for common items. Are we sure about the volume numbers shown on DF2012:Weight , as it looks like you should have 83 blocks per minecart rather than 100. -- UristDaVinci 05:08, 26 June 2012 (UTC)

Physics

The physics section could use an overhaul/rewrite, with some numbers for track friction, track stop friction etc., since the first such are now available. Well, some have been available for almost a month, some are more recent. I can do at least some of it myself, but off to sleep for today. -- Snaake 23:32, 7 June 2012 (UTC)

I added a section on controlling speed and am using the m/s units to mean tiles/step as I couldn't see any already in use standard for speed. This is the units used in the second post you link, I think it is pretty good. --Billw 12:39, 13 August 2012 (UTC)

Weight

Seems like it doesn't affect their speed nor it does affect their slowdown. An empty feather tree minecart (lightest) seems to have the same speed as a platinum one filled with platinum nuggets (heaviest) when pushed/launched from roller. Also, they both are unable to scale more than one z-level when launched by a single-tile top-speed roller.--HYBRID BEING 07:52, 25 February 2013 (UTC)

I wouldn't be surprised if rollers aren't affected by weight. They are a relatively new feature (see ^Bug:5911 for an example). According to the article, minecarts do accelerate and decelerate based on weight, but not when guided by dwarves. They also aren't affected by weight when Skipping. Feel free to add a note of this to the article if you like (for example, under this section). --Lethosor (talk) 22:23, 25 February 2013 (UTC)

I didn't test driving them but as i said they moved at the same speed (i failed to notice the expected from such different minecarts difference in speed, at the very least) when pushed, no rollers involved. --HYBRID BEING 10:14, 26 February 2013 (UTC)

Magma-Safe

It turns out that nether cap minecarts are not magma-safe and can not be used for hauling magma.
