I lived by the Livonia Avon & Lakeville at one point. In short.
The c424's they mainly used consist of the following:
421 and 435 - lettered as Western New York & Pennsylvania
422 - lettered as Bath & Hammondsport
423 and 424 - both lettered as Livonia Avon & Lakeville
The LA&L owns 2 nearby railroads called the Bath & Hammondsport and the Western New York & Pennsylvania.
Nice work.
