The Legacy H7 does come with the Vanderbilt tender, The only things Lionel changed were the electronics and the road number (Incidentally according to info I have the Legacy H7 road number, 1578, in real life had a rectangular tender in the post 1930 paint scheme, not a Vanderbilt). The Lionel 6-11299 is a C&O H5 mallet. Very different engine from the H7. The H5's had the small rectangular tenders and I don't think they ever got a Vanderbilt. If any did it would have been a 12,000 gallon version. The Lionel version is a 16,000 gallon.
