GRJ: version1.54 of Legacy corrected a bug that happened in version 1.53 concerning 50Hz application. All versions up to 1.52 and now 1.54 can be operated without problems in 50Hz Environment.
NICK12DMC: only few Lionel vehicles were equipped with Trainsounds operational with TMCC commands. The two mentioned cars above are examples. I used them to remove the electronics and to install these devices accordingly in a Weaver streamlined car and in a brass caboose.
