Iron horses cannot run all the time, as they occasionally need some rest and rehabilitation. On February 16, 2018, BNSF Railway ES44C4 8395 joined some others in the "stable" for routine maintenance at the Diesel Shop in Barstow, California. This is the BNSF's primary locomotive shop for its rail lines in California. Photographed on railroad property with permission and full Personal Protective Equipment (PPE).
