This was my view from the engineer's seat while performing switching at Mauriceville, TX. We are kicking cars into the four tracks seen in the picture in order to put the train into what was called "station order." We would then go from station to station setting out the cars along the way. The cars for station A would be next to the engine, then station B cars behind them, and so on. This yard was on our Orange Subdivision branch, and most of the cars we handled were either LDPE plastic or hazardous chemicals produced by Chemical Row, one of the largest chemical complexes in the world. We handled HCN (hydrocyanic acid) cars routinely. These cars were so dangerous, that they had to be handled a minimum of 25 cars from the engine or caboose. My next door neighbor, and SP engineer, proved that this distance (more than a quarter of a mile) was insufficient. He was handling some HCN 30 cars behind his engine when he hit a sun kink at 40 mph, derailing the HCN cars. The fireball destroyed his engines over a third of a mile away, and wiped a small East Texas town off the map. He and his crew escaped by running ahead of the train once it came to rest.
