    Did some of the 4500s come with Boxpok drivers from Baldwin?

    I have only seen 4500s with Baldwin universal disc drivers.

    4-8-4 SLSF 4500-4514 had Baldwin disk drivers.

    Any pictures showing the rest of us what they look like? :)

    Really just looking for more steam locomotive images.

    Here is a link to an on-line article about drivers that explains the differences.

    https://www.steamlocomotive.com/types/drivers/

    It has a link to a Boxpok driver with spoke wheels on the same locomotive for comparison.

    There is a prime example of a Baldwin disk driver as fitted to 4-8-4 SLSF 4500-4514 for comparison at this link.

    Another sterling example of Boxpok is at this location.

    If I recall, there was a diagram of a Boxpok driver on Frisco.org somewhere.
