reactor fluid car

I have a Lionel 6315-2 (6-16154) reactor fluid car that has lost about 1/4 of its purple fluid. There are no apparent leaks that I can spot. Has anyone else encountered this problem, and if so, is there a replacement available?

I have all 5 and have not seen any leakage or evaporation.

My purple car has lost fluid also, although not as much as yours, maybe an 1/8. I haven’t noticed any leaks on mine either.

A the time of their release there were stories of the cars freezing and cracking in severely cold regions.
