Steam Locomotive sighting on Rte 128 Waltham

On Thursday 3/31/16, while I was driving north on rte 128 in the Waltham area, I passed a southbound flat bed truck hauling what looked like a boiler without cab sitting on 0-4-0 driving wheels. As our closing speed was ~120mph, I couldn't get any detail other than it looked like it might have been a narrow gauge locomotive. Anyone know the story?

Hi
The locomotive you saw could have been ex New Haven Trap Rock # 38 , because she was recently sold . Pat

I Googled some imagery for NH Trap Rock 38 and it's a good candidate for what I saw although I think the saddle tank was also removed. Thanks!

I don't know if that was the 38 or not but I do know the Trap Rock #38 was bought by one of the volunteers at the Valley RR, and is to be restored at his home.

Hi, guys probably not the 38 since I moved the 38 to my house today in CT.

Nothing like primary source data! One of the things love about this place.
