Steam & Excursion > Old Days Steam Engine Question

Can someone educate me on how things were done on the early steam power before injectors ?
My understanding is that water was injected via a mechanical pump driven as the locomotive moved.

If that be the case, how were locomotives layed over or held in a terminal without moving and still be able to induce water into the boiler ?

 

Yes, pumps were used, driven off the crosshead or off a crank attached a siderod. 

It was necessary to run the engine to feed water.

Some pictures can be found here in a post about 5 years back.

Here are two pics of the 1875 Glenbrook at Nevada State Railroad Museum last May.

​It has a working crosshead pump on the engineer's side and an injector on the fireman's side.

​The injector was invented in 1858 so most locomotives built during the cilvil war had one.

​Prior to 1858 the croosshead pump was the primary method for injecting water and the engine had to be moved back and forth to get water into the boiler when it was not working a train.
