The design of a paint booth system for a rail refinishing facility may differ significantly depending on its primary focus, such as refinishing parts versus manufacturing entire train cars. In the case of refurbishment or refinishing, a practical solution may be to divide a large 150-foot-long paint booth into smaller sections using divider doors. This adaptable arrangement allows for optimal utilization of the booth, combining the space for painting entire rail cars or locomotives or utilizing specific sections for parts painting. By doing so, the facility can minimize energy consumption by activating only the necessary areas and avoid running the entire paint booth system when only a smaller space is required.
