[Intro] [distorted electric guitar riff, driving drums] [Verse 1] [palm-muted guitar, bass, and drums] This freight inside my chest won't slow Been burning coal since you let go Every sleepless night, a thunder and sound These wheels keep turning and wearing me down Can't pull the brake on what I'm feeling The engine's hot and the pressure's building [Chorus] [full band, open power chords] I'm a runaway locomotive Can't stop this heart from going Steel on steel and grinding through the pain Like heavy metal rolling down these tracks There ain't no bringing this wreck back I'm a runaway locomotive Bleeding smoke and strain [Instrumental Break] [distorted guitar lead melody] [Verse 2] [drums and bass continue, guitar becomes more rhythmic] My hands are shaking on the throttle now This boiler's screaming but I don't know how To let off steam or ease the load I'm hauling heartbreak down this road The coal keeps feeding all this fire But I just keep on moving higher [Chorus] [full band intensity] I'm a runaway locomotive Can't stop this heart from going Steel on steel and grinding through the pain Like heavy metal rolling down these tracks There ain't no bringing this wreck back I'm a runaway locomotive Bleeding smoke and strain [Bridge] [drums drop to half-time feel, clean electric guitar arpeggios] Used to have a station, used to have a home Now I'm just momentum and diesel and bone Can't derail what's already broken These pistons pump with every word unspoken [Chorus] [maximum volume, heavy crash cymbals] I'm a runaway locomotive Can't stop this heart from going Steel on steel and grinding through the pain Like heavy metal rolling down these tracks There ain't no bringing this wreck back I'm a runaway locomotive Bleeding smoke and strain [Outro] [guitar riff fades] This freight inside my chest won't slow Been burning coal since you let go
