Powered rails don't work if minecart is really slow

Steps to reproduce: Build a long track of rails, place one powered rail at one end and the next one many blocks away, until the minecart barely reaches it after being moved by the first powered rail. If the minecart is really slow (multiple seconds per meter) when it reaches the rail, it doesn't get sped up. The rail just works as a regular rail.
I currently can't attach a video, because my PC doesn't work and I'm playing on my laptop (too slow). If someone can reproduce it and make a video, that would be great.

Could you attach a screenshot of your setup? It is hard to reproduce unless we know what sort of minecart it is, what is in it, how many powered rails accelerate it originally, etc.

The problem is that a screenshot would look like this. It's a really far distance between.
I've usually put a powered rail every 10 blocks, but as I didn't have enough gold for that (for the achievement "on a rail"), I looked at where the minecart stopped and put a new one exactly on that spot. But then it didn't work, which is why I created this bug report.

Confirmed for 1.9.4.
I reproduced it as follows:

  • powered power rail at z=26

  • powered power rail at z=105

  • rails all the way between, no height differences and some rails at higher z

  • block at z=25 (to bounce a minecart back when it goes to the end of the track)

  • minecart at z=28, push in negative z direction and enter quickly
    Result: Minecart bounces off of block (as expected), gets really, really slow above z=100 and passes the powered rail without being affected by it (even slower).

Also confirmed for 16w21b with the same setup.

Could please the status of this bug report get corrected? I told how to reproduce.

Is this still an issue in the latest snapshot 16w44a? If so please update the affected versions.

This is an automated comment on any open or reopened issue with out-of-date affected versions.

Affects 21w10a

To reproduce:

  1. Get some flat land

  2. /fill ~ ~ ~ ~100 ~ ~ rail

  3. Replace the 1st and 79th rails with a powered rail (/tp ~78 ~ ~ while standing on the 1st rail)

  4. Power the 79th (powered) rail

  5. Setup minecart launcher with a block and button using the 1st rail at the start

  6. Sit in a minecart and launch

Confirmed in 1.20 using @Skaijie's method
