When Lionel does the new Boy Tenders, they may want to move the IR board to the center of the tender to allow greater spacing between the pick-up rollers.
Does anyone have the new sound Water Tenders to tell if the pick-up rollers are spaced further apart.
OR … Lionel could easily put female plugs in the rear of the engine and the front of the tender connected to the center pick-up rollers. These would allow buyers to run at wire from both female plugs to connect all rollers. The plugs would not be visible unless they were used with the wire tether. This optional connection would "bullet-proof" the steam engines and avoid different manufacturers' track issues.
Sincerely, John Rowlen
