Only Legacy Lionmaster engines that were produced after around 2012 when the sensors were added to the locomotives.
An option if you can find one is the 6-83519 REA Scale Sensor Boxcar. This boxcar was made to add sensor capabilities to earlier Legacy engines without a sensor and to a lesser amount TMCC engines. I've been told Lionel has a lot of these because folks didn't understand what the purpose was or how they worked but so far I haven't seen them at the warehouse sale.
