Here we are riding the steam locomotives going from refuelling back to duty
It is the beginning of the fourth and last outing for the locos, of the first of two UVHJ 150 years celebrations
Location still Uddevalla, Sweden
First runs DJ No.10, a H3-class swedish steam loco
We ride with BJ No.130, a B3-class swedish steam loco
Stop on bridge, before go back to platform for passenger cars
Did you turn up volume?
Now our No.130 runs first, down to platform
Close regulator, stop steam flow, and rolling
We need good fire, because departure from Uddevalla is soon and is uphill
Departure!
This valve regulates steam to air pump
And this is open valves in cylinder, to decrease power output
It is a little bit like using the clutch in a manual car for a smooth drive engage
Fully open regulator
This operates to valves to cylinders
We go backwards and use approx. 30% cylinder filling
Here driver increase power output by increase cylinder filling - more steam is consumed
Tunnel!
And steam locomotive features no electric light
For this short ride in dark we did not bother the gas lights
Did you turn up volume?
The railway we are celebrating was iniatially narrow gauge
but later on rebuilt into normal - 1435 mm
You see cylinder filling is decreased as the steepest uphill is climbed
Here maybe as little as 10%
Here is a rod connected to wheel which drives a pump
It pumps high viscosity oil to cylinders
"Ånglådan" says this gauge - telling how much pressure is sent to cylinders
7 bars here and is a product of regulator opening and boiler pressure
With so little cylinder filling, steam consumption is rather low and fireman gets an easier job
Always need to watch pressure and water level inside boiler
The left gauge shows break pressure
Here fireman check fire for holes
Here he intends to put charcoal in holes, to retain pressure
Check for holes again
and cover them
If all holes were covered, pressure will rise immediately
Driver close regulator
Fireman uses the opportunity to inject water from tender to boiler
Listen through the noisy enviroment for water flow
Now okay! Water flows and injector gets cold, which is felt by hand
Leave to doors open for secondary air, which has a cooling effect
This steam loco is the only remaining B-class
that hasn't been rebuilt with closed cabine
Wellknown station from previous videos - Ryr!
Here meeting with a commercial running train
To be continued...
