Anchors for a flatcar load would be more like those used on large naval vessels and ocean going ships since the late 19th century, having two large flukes attached to a shank with an eyelet for attaching the anchor chain. At about 10 tons or so each, four such anchors would make a good flat car load, held in place with wood blocking. The attached photo will show the scale of these anchors, from a person sitting by it.

There were (and in a few cases still are preserved) sailing ships built in the late 19th century and even a few steam axiliaries built in the early 20th which carried the sliding stock anchors. Balclutha, 1886, Connell & Sons, Glagsgow (one of the first 20 or so steel-hulled sailing ships[0]) is currently resident at the only floating national park in the US and its territories[1]. The more modern naval anchor doesn't cat up like the earlier design, so even the early steam auxiliaries with the more traditional hull shape carried the earlier design of anchor.
