Sperling Railway Services Inc.

March, 2019

Sperling Railway Services, Inc. manufactures maintenance-of-way railroad track equipment that it sells to large rail companies.

One piece of equipment it makes is an 80,000-pound plate-laying machine that crawls along a railroad bed at about a mile an hour, automatically placing steel tie plates onto new or existing railroad ties as part of the process of replacing track.

With the machine moving at such slow speed, the crew running it can forget it’s moving at all—as can workers and equipment on the track in front of the machine.

Sperling needed something to make sure the machine would stop in time to avoid collisions. By replacing its mechanical stop bar with PRECO Electronics’s Preview Sentry, the company improved its ability to protect both people and machines – and keep the repair crews moving at full steam.
