nymph and phantom -- wiliam mason

greeting train buff and experts:

yesterday i purchased two 1/2 plate ambrotypes of two locomotives:
the nymph
the phantom

made in Taunton Mass by William Mason

The images are pretty amazing, each has several people perched on or in front of the locomotives
one has a pic of Mason himself, i believe

I am looking for any historical information about these two engines,
where they were used,
when,
any historical connections perhaps to Lincoln? or Civil War?

Many thanks for any info you can provide

I will be glad to send jpeg to anyone who provides some leads

many thanks,
please join with me to pray and WORK for peace on Earth
God bless
