L.N.E.R Pacific Locomotive

by Mr. Norman Robinson

<i>[[The Modelmaker]]</i>, Volume 9, Number 10, October 1932

I am sending you a photo of my 3/4 inch scale L.N.E.R. Pacific type locomotive which may be of interest to readers of [[The Modelmaker]]. I have been at work on this loco for the past two years, just spare time, and it is almost complete but for a few minor details such as handrails and lettering.

I purchased the blue prints, cylinders, wheel castings and boiler tube, 4-1/2 inch diameter, from England. The rest was made up from plate and rod stock.

'''Specifications'''

* Gauge: 3-1/2 inch
* Scale: 3/4 inch
* Cylinders
** Bore: 1 inch
** Stroke: 1-5/8 inch
* Ports
** Steam: 3/8 inch long, 1/8 inch wide
** Exhaust: 3/8 inch long, 1/4 inch wide
* Bogie Wheels: 2-1/4 inch diameter
* Driving Wheels: 4-15/16 inch diameter
* Trailing Wheels: 2-3/4 inch diameter
* Tender Wheels: 2-7/8 inch diameter
* Valve Gear: Walschaerts
* Boiler: Fire Tube
** Boiler Tube: 15-1/16 inch long by 4-1/2 inch diameter
** Flue Tubes: Copper
*** Eleven @ 1/2 inch diameter
*** Two @ 3/4 inch diameter
* Fire Box: Hard Bronze with twenty 5/32 Bronze Stays on each side
** Size: 5 inches by 5-1/2 inches
* Grate Area: 27-1/2 square inches
* Steam Pressure: 75 lbs
* Length of Engine: 34 inches
* Height of Engine: rail to top of smoke stack, 11 inches
* Fiitings in Cab:
** 1 inch diameter steam gauge
** 3/16 inch glass water gauge
** blower valve
** whistle valve
** throttle valve
** one check valve
** two checks on boiler sides (one for mechanical pump and one for hand pump)
** reversing lever quadrant in cab

I have had this engine on test a few times now and she behaved very well keeping the safety valve popping all the time. I can raise steam from cold in six minutes, which I think is very good because the boiler holds more than a gallon of water.

On its first test I had it steaming for 7 hours. I do not know how much it will haul but on a poor track and a board laid on the top of the tender it pulled 3 adults. I am now building an out-door track 80 feet long so I can give it a more thorough test. I have also nearly completed a passenger car which is 3 feet long and will carry four passengers. When I get everything fixed up I will send you some more photographs, and particulars.
