- IAIS 6988 and 7081 were brought to the US by Railroad Development Corp. to test the market for modern imported steam in the United States. See the QJ page for more information.
- During the summer of 2011, both engines were modified to connect with tank car IAIS 8000 as an auxilliary water tender.
- For Train Festival 2011?, 6988 received an "Americanization", removing some of the more Chinese features of the engine to make it closer to a standard American design. Amongst the changes were a single headlight, US whistle, removal of the shroud around the exhaust stack, and changing all red parts to black.
