In 1967 LEGO released 4 Trains sets. The largest Trains set from 1967 was
116 Starter Train Set with Motor with a piece count of 439 and a retail price of $16.00. The current estimated value of all these Trains sets from this year is about $2,075.47 which represents a 8816.8% growth.
LEGO Trains is one of the longer running themes that dates back from 1966 and ran up until 2006. During its run there were multiple sets released running on various power platforms from 4.5volt, to 9 and 12 volt sets. Later in 2011 LEGO released additional train sets using RC and Power Functions controllers under different themes like City.
1967 LEGO Sets
In 1967, LEGO began to better define and redefine how LEGO sets were scaled. This was an important change that we still see in modern LEGO sets today. During the 1960’s the size of LEGO sets and scale of the models had changed, mostly growing larger over time. With the mid 60's introduction of model sets, known as Model Makers in the US, these sets were based, not on the 1:87 scale of the Town Plan, but on the larger scale of the 2 x 2 wheel. The train sets introduced in the previous year and a series of truck models in 1967 were also designed around the 2 x 2 wheel and from that point on all new development was based on this larger scale. The LEGO System had changed from the loosely scaled Town Plan to a larger, and much more consistent, scale. A scale that integrated nearly all the sets and one that is close to the mini-fig scale of today.
