The MPI HSP46 is a four-axle AC-traction diesel-electric locomotive for commuter trains, designed and assembled by MotivePower, Inc. It meets EPA Tier 3 emissions standards. The launch customer is the Massachusetts Bay Transportation Authority (MBTA), whose first unit entered revenue service in April 2014.
The MBTA Board of Directors voted, on July 14, 2010, to approve the purchase of 20 new HSP46 locomotives from MotivePower, Inc. These are powered by GE GEVO-12 diesel engines from GE Transportation Systems, equipped with a static inverter for head end power, and capable of meeting the stringent new Tier 3 emissions regulations. AC traction systems, prime movers, head end power equipment, and computer systems are supplied by GE, while MPI supplies the brake systems, air systems, and cooling systems.
On July 27, 2011, the MBTA released images of a new paint scheme which will be applied to the authority's HSP46 fleet. It was chosen by the general public in an online survey.
Yeah, Oh Yeah, Yeah, Oh Yeah!
Go To A Party, We'll Crash It
In A Hotel, We'll Trash It
Got A Bottle, We're Drinking
Got A Yacht, He's Got A Yacht?
We'll Sink It
Chorus
There's Always Trouble
It Follows Us Around
Everywhere We Seem To Go,
Every City, Every Town
There's Always Trouble
It Follows Us Around
1...2...3...4....
Who's That Knocking At The Door?
Zap, Pow, Biff, Bang, Holy Cow!
Someone's Gonna Get It,
And They're Gonna Get It Now
Smack, Crack, Bish Bash, Heart Attack!
Someone's Gonna Get It,
And They're Gonna Get It Now
It's A Short Walk, We'll Cab It
Got No Invite, We'll Blag It
Got A Light Switch, We'll Fuse It
We've Got A False Box
And We're Gonna Use It
