Lionel Vision Line Big Boy. My first and only Lionel Vision Line. I forgot to record the pop off & blow down smoke! Pulling all MTH Premier Reefer cars (3 PFE 6packs) and other misc. reefers with the exception of 5 Lionel reefer cars. One PFE 3 pack are Vision Line and have sound. The other two Lionel reefers have sound for a total of three sound cars. Running on the blue line.
