I have a list of all the elevators in Massachusetts but some of the labels are unclear under E_TRAC there is H-Hydraulic T-Traction but there are a lot of other letters and numbers too. The same goes for type of elevator P-Passenger F-Freight but what is a K? here is a link to the list https://drive.google.com/file/d/0B3O3ASn76hO0TlZfOXhiN3k4ZEk/edit?usp=sharing
