Gotta love how it suggests the train will run in reverse if the battery polarity is reversed, but I thought the design of Plarail contacts made it virtually impossible to actually fit the battery in reverse? I tried it once just to see if I could get an engine running in reverse for a shunting loop [would have looked better running backward] but alas, no, because the positive contact [on the motor unit] was recessed to prevent such an occurrence, by making sure you had to put the raised 'tip' on the positive end onto the correct contact to fit.
