e-Rail Safe Certified Dealers
e-Rail Safe certification is required to enter rail yards and facilities across the United States. Without this certification, access to rail yards can be denied, causing major problems for your business. If technicians cannot enter the yard, loads can be lost to unit shutdowns, costing you money and customer loyalty. Thermo King dealers are e-Rail Safe certified, allowing them to access all rail yards nationwide.
