The city acquired 25 motors from the SIRT in the 1950s. Most were rebuilt for ise on the BMT division, primarily the Culver shuttle and Franklin ave shuttles. Some were retained for use as work cars and yard offices. The cars that ran on the two shuttles had the center headlight removed as part of the rebuild and after the rebuild, they were repainted and had the new logo. Here are a few more photos. You can see where the center headlight was removed as there still are what look like the base of a bracket which held the light
You can see in the photo below the details to mount the center headlight
