It's a little confusing because the TMCC Verandas came in a box labelled "Veranda Big Blow UP" (see photo) but I associate that name with the 3-unit turbines with a lead unit, turbine unit and fuel tender. AFAIK Lionel never made any of those, while MTH did. But in any case, the Veranda Turbine was only two units with the turbine in the main forward one.
