This is one of the first structures introduced by Bachmann and its production spanned over three decades. RS-7 was the first designation given to this station when it was first released in 1950, and on the box it was labeled "Passenger Station."
The following year Bachmann would release the RS-8 station, and later issues would rename it the "Suburban Station," which would remain its title until production ceased in the 1980’s. In addition, the box for the RS-7 is about one inch taller than the RS-8. This is because in the earlier issue there was a one inch tall box insert that is located beneath the contents. The RS-8 box would not have this insert.
Aside from the No. RS-7 box, the No. 1706 box is the rarest of these boxes having only been available from 1964 through 1966.
