Need a little assistance on this set??

[Super]

I had seen this listing several times. Looks like there have been some wheel swaps on the orange and brown train engines. I am not totally sure but the N700 in the foreground looks to be a remote controlled train but don't see a remote, maybe I am wrong. Looks to be two complete 3 unit N2 Shinkansen Max's. Another N700 with 3 middle coaches and a Marine Liner. You don't normally see the Japanese trains listed on the US Ebay.
