Is this the longest simple electric train track in the world?

In 2014, Amazing Science published a simple electric train video that demonstrated how an alkaline battery and four strong magnets could be propelled through a coiled copper wire track.

This video by Mr. Michal takes this simple electromagnetic train to the next level with a 20-meter (65-foot) track of wire. Watch as four battery + magnet ‘trains’ travel over, under, and around what might be the longest simple electric train track in the world.

How did he do it? Mr. Michal writes:

Everyone can make a simple electric train at home… Just a little time and you have your own train station with various trains and wagons and lots of wire tracks. And full hours of fun can begin… You only need these three parts.
1. copper wire raw or aluminum wire
2. battery ( AAAA, AAA, AA, CR2, 123, C AND D )
3. and two neodymium magnets ( it must be larger in diameter than battery )
