North Bank Lines has provided a Fall 2018 newsletter with the following notes:
There are a few minor updates to the steel caboose project. There are about 250 reservations, so the cuttoff for the builder will be coming up soon. If there are any pieces you would like, please let us know soon.
The SP P-12 project is very short on reservations and may be canceled. If you would like one of these unique Pacifics, or know someone interested, please let them know so we can help move this forward.
The other projects are still in the early planning stages (CB&Q/GN/NP 2-6-6-2s, WP 2-6-6-2s, SP 4-8-0s) with revised announcement pages expected in the future.
