Vintage Awesome Lionel The Midnight Flyer 6-1990 Mystery Glow Special


The Lionel "Mystery Glow" Midnight Flyer electric train set (SKU: 6-1990) was originally released in 1979. Some sources may mistakenly list the year as 1990 due to the "1990" in the model number, but it is a vintage O/O-27 gauge set. This was also sometimes referred to as the Toys "R" Us Midnight Flyer Set.

Here are the key features and components of the set:

Engine: The set includes an 8902 steam engine, which is a DC power only engine that runs in forward and reverse.

Cars: The freight cars included in the set are:

An Atlantic Coast Line slope-back tender

A 9340 Illinois Central Gulf gondola

A 9339 Great Northern boxcar

A 9341 ACL caboose

Condition: Many sets found today are used, and can have some damage, such as a broken wheel on one of the cars.

"Mystery Glow" feature: The set's nickname comes from its ability to glow, although some sources note that the glow can be very dim.

Since the set was released in 1979, the value of a used set depends on its condition and whether it's complete. Listings on eBay show prices ranging from $40 for a used and damaged set to over $100 for a used set in good condition. A "new old stock" set that has never been used could be worth more to a collector.
