MP E-unit Cab Boosters
This page is dedicated to MP's fleet of E-unit booster units. The MP was the owner of xx E-unit cab units, all of which were purchased new by the MP. I am listing the foremer I-GN and SLB&M units as MP units because these roads were MP-owned subsidiaries by the time of their purchase and operationally were considered MP units. The assignment was apparently only on paper. All MP e-unit boosters featured a "B" alpha suffix to differentiate them from the cab unit with the same number. It is not known if this was painted on the side of the booster units.
