This is the real money train.

There’s been a huge increase in A train riders heading to Aqueduct, thanks to the two stations that serve the popular new racino, according to MTA statistics.

Ridership at the Aqueduct/North Conduit Avenue station was up 99 percent over last year, from 238,000 to 474,915.

And at the nearby Aqueduct Racetrack station — open only on race days — the number of users climbed 83 percent.

The gains are even more notable since the racino — which has slot machines, electronic table games and restaurants — didn’t open until late October 2011.

Overall, ridership grew 2.26 percent, to 1,640,434,672 riders, the stats show.
