At some point the electrical systems on the 480s in Chama were reworked. All the Pyle switches are gone and modern plastic light switches are now in place. The class lamp switches are gone too; in fact the conduit for the class lamps and number boards was all out of service (probably when conduit was reinstalled after various 1472s) until we began reworking it last winter. You’ll notice 487 and 484 now have conduit to the class lamps again and 484’s number boards are illuminated when the dynamo is on.
