Thanks for your response, Mack. I'm confused though. Is there a difference between a 2nd "piece and a 2nd "section"? During the "War Years" busy companies were given a second unit that was designated with a small '2' following the company number on the pumper/truck. Is (was) this the same as a 2nd "piece" that you are describing? If not, please explain the difference. Thanks in advance.
A two piece company operated with two apparatus staffed by one crew with one officer. The two apparatus operated together with one unit identity (for example - Engine 99). Most commonly, this would be a pumper and a hose wagon, but it could also be two pumpers. To your original question, Engine 158, at that time, would have been Engine 158's engine (1), and Engine 158's pumper (2).
Second section companies were (none at present) two fully and separately staffed companies, each with their own fully equipped apparatus, operating from the same station and sharing the same area and assignments. They were established to increase the availability of very busy companies in key locations. Their shared identity was distinguished by one (1) or two (2). For example, Ladder 99-1 and Ladder 99-2 and spoken as ninety nine, one and ninety nine, two.
Anticipating your next question, yes, a first or second section company could also be a two piece company. It was actually quite common among the early two section companies of the horse drawn era.
Two piece companies have essentially been phased out although the six engines that staff the six satellites are technically a pumper and a hose wagon with one crew. Some of SOC support companies also operate with two apparatus.
Second section companies do not presently exist although a relocating company may be referred to as a second section of the company that they relocated to, especially when more than one company has been relocated to the same house. (Example, the first, second, and third company to relocate to a house might be differentiated by: Original Engine 99 would be the first section, the first relocator would be the second section, the second relocator would be the third section, etc.)
Hopefully the dispatchers can elaborate if things have changed.
