Since my child has outgrown Plarail! I'm selling the trains, tracks, and scenery I collected during a 6-year Plarail boom. SL & Freight Cars * Tested and working! Batteries: Size D x 1 Since this was used by a child... please refrain from purchasing if you are overly concerned about condition. However, I think my child used them carefully♪ I've wiped them down with alcohol, but some small dust particles may remain (;_;)
