Is the monorail crafting now endless?

I love(d) doing the Monorail one a week but I'm not sure how I feel about doing it over and over. Currently towards the end of round two for this week. I don't need the tracks, so that's not a draw. And getting 5 donuts again is "ok", but I think I'd rather just have those characters earning cash elsewhere so I can later convert it into donuts. I also occasionally tap one to many times on the dump or whatnot and end up tapping on Go To and being whisked away to Milhouse or Lisa, who are way across town busy with this event.
