I have that very locomotive on my HO train set
If you’re gonna do that, I would also add some weight to the rear. It’s 2wd so it’ll need the traction over the rear tires. A couple bad engine blocks in the bed would do the trick I bet
waiting for the smack down.
Pics??
Not on hand. I’ll have to try to find some on my laptop.
I built this nearly 12-13 years ago. An L shaped layout, 8 ft on each side. DCC compatible and controlled. It’s currently taken apart and shoved into a storage shed. It’ll go back together as soon as the garage is finished
???
I think it's a GP38
Sent another prayer your way Bill.
It was never common knowledge to Americans, either -- except for a few Americans in the vehicle lighting industry.
1940: the first standardised sealed-beam headlamp, a 7-inch round unit, 6 volts, 40/30 watts (high/low), called the 4030.
1950 or so: wattage is increased to 50/40 (high/low) and the new lamp is called the 5040.
1956: aiming pads (three little protrusions in a triangular formation on the front of the perimeter of the lens) and a filament shield (to block stray light that causes backdazzle in bad weather) are added. Wattage stays the same at 50/40. 6v unit still called 5040, new 12v unit called 5400
1958: The reflector focus is improved. Wattage stays the same at 50/40. There is now an effort at a standard system of nomenclature: the first digit indicates the size, the next digit indicates the service application (0 for headlamp), the next digit indicates the revision/version, and the final digit specifies the subtype (high/low beam headlamps, known as "type 2", have a 2 as the final digit; high-beam "type 1" headlamps have a 1).
For whatever reason, the first digit for 7-inch headlamps is "6", while the first digit for the new 5.75-inch headlamp is "4". (the other major market where sealed beam headlamps are used, the British Commonwealth, uses "7" for the first digit of 7" lamps and "5" for the 5.75" lamps). So in the American system, the new 5.75" lamps are 4002 for the 37.5/50w high/low beam (4005 for the heavy-duty version), and 4001 for the 37.5w high beam. The 6v 7-inch unit is now called 6006, and the 12-volt unit is called 6012.
This system of nomenclature breaks down very quickly as the industry seems to make and break rules at random:
1970: the 7" headlamp is upgraded to 60/50w and is now designated 6014. Heavy-duty or long-life versions by various makers are 6015 or 6016. The 5.75" high/low beam headlamp is upgraded to 37.5/60w and is now designated 4000. A heavy-duty, vibration-resistant/long-life version of the 4000 is called the 4040.
1975: the small rectangular (165 × 100mm) four-headlamp system comes along. The 40/60w high/low beam is 4652 and the 50w high beam is 4651 ("46" makes sense because those metric dimensions are more or less 4" × 6", but now we're using the first two digits for the size…)
1977: the big rectangular (200 × 142mm) two-headlamp system comes along. The 65/55w lamp is called 6052 (now we're using "6" for something other than a 7" round lamp, and a random "5" to differentiate from the "1" in 6012, but even though we've got about the same filament wattage as the 6014 lamp, we're using "2" as the final digit…).
1977 or so: GE buys a couple million 60/55w H4 halogen bulb burners (just the glass capsule with filaments inside) from two European makers and begins making halogen sealed beams: H6014 7" round and H6052 200 × 142mm rectangular. Wagner follows suit around 1980, only they call their rectangular unit H6050 (just whatever, pick any digit; they're all good).
1979: US regs change to allow double the high beam intensity. New 5.75" round high beam is a 50w item called 5001. Halogen version is H5001. Halogen small rectangular 50w high beam is H4651.
1984: US auto industry wants lower-wattage headlamps so they can use cheaper switches and wiring. US lighting industry devises a homegrown 35w halogen capsule. Poorer-but-still-legal performance. Now we've got the H6024 (7-inch round halogen 35w high/low beam…except Philips calls theirs H6017), the H5006 (5.75" round 35w high/low beam), the H4656 (small rectangular 35w high/low beam), and the H6054 (large rectangular 35w high/low beam).
1987: Truck-duty extra-long-life halogen sealed beams: H5024 7" round, H5054 large rectangular, H5062 and H5051 small rectangular, and H5501 and H5506 (or H5009) small round—now we've decided the first digit doesn't mean anything and the rest of them are pretty much random.
1992: higher-performance sealed beams with what used to be the standard wattages (65/55 or 60/55 high/low), but we keep the designations adopted for the low-wattage lamps and just add whatever suffix each individual maker likes. GE calls their "High Output" lamps H6024HO, H6054HO, and H4656HO. Sylvania calls theirs H6024XV, H6054XV, and H4656XV. Wagner calls theirs H6024BL, H6054BL, and H4656BL.
So now there's pretty much nothing left resembling any kind of standard numbering system.
Notes:
1. Years are approximate in this longer answer than you probably wanted, and it doesn't go into some of the little-known but really cool sealed beams made in places like Japan, the UK, and the Netherlands.
2. I sometimes wonder what it's like to think of car lights in terms no more complicated than present/absent, works/doesn't, on/off, bright/dim, and white/red/amber.
Thank you Dan. I am fine with it being long. No worries, and no complains from me.
I remember my dad had a 1978 Toyota Carina, it had 4 of the small 5,75 inch, but it was not sealed beam. It was glass and reflector like a sealed beam, but made for these bulbs, Headlight Bulbs - Asymmetrical Bulbs Double Filament Manufacturer from Jaipur
Those were extremely common over there in the lalaland where I come from. In the lalaland over here I guess they were not as common.

That Carina would have had sealed beams in its home Japanese market, but European-type headlamps were put in cars exported to countries where that type was either required or most commonly used. That's an R2 bulb you've linked. Tungsten non-halogen, 45/40w high/low beam in 6- and 12-volt versions; 55/50w in the 24-volt version used in European trucks and buses. It was almost 100% universal in European headlamps (that is, headlamps built to comply with the European regs, no matter who built them or where) starting in 1957. This bulb came in white and selective yellow.
When the Brits and Europeans devised the world's first halogen 2-filament (high/low beam) headlight bulb, the H4, in the late 1960s, they kept the filament geometry compatible with that of the R2, so it was an easy matter to make hybrid bulbs: an H4 burner on an R2 base. Thus were old headlamps updated to halogen technology just by changing the bulb.

The P45T socket as it is called did not come with H4 for a long time that I know of. The H4 started to become popular in the 70ties in Norway, but with the P43T socket. I did not see a H4 on a P45T socket until late 90ties. I have no idea when they came, but they were not common in Norway until late, and they are still nothing you can get in gas stations, it is a bit of a special order from a few companies that carries them.
Actually, the R2 you refer to, that is something I have never heard used in Norway. We used to differentiate them by the base, P45T, or BA15s for example, except the halogen bulbs which was H1, H2 and H4 for many many years. Europe has not used the American number system like 1057, or 1004, or whatever as far as I know. We used for example 5Watt BA15s, BA I think stands for bayonet, 15 is the diameter of the socket in millimeter, and s is for a single philament. A 10Watt BA15s would be the same bulb but with a 10 watt philament.

There is another European lamp that was used a lot too, but I think it is a bit older than the P45T socket. It is the BA20d socket. BA20d 24 VOLT 45/40 WATT ASSYMETRIC HEADLIGHT REPLACEMENT 398 X1 BULB
Since my dad was a truck owner, and used to plow snow, he always had extra lights since the plow was hiding the original headlamps. And I still have bulbs and lamps laying at home in Norway from those days.
Both the P45T and the BA20d sockets.

It is also funny this "tungsten" you mention. I have many times thought about that, why you adopted the Swedish name for Wolfram. Tungsten consist of two words, Tung and Sten. Tung means heavy, and sten means stone. So, heavy-stone.
Bill
First? Really?
Looks like great time was had by all!
Not really. Just browsing. Plan on going back to sleep.
All screwed up timewise.
3 hours off kilter,being in vegas and the time change just cant seem to sort myself out.

How did Vegas go?
Morning. Waiting for the chief to get up so I can put laundry up, shave and catch a helipoter out of here.
Bet it is good to get home again Steve. Have to ask why wait for the chef?
Got wait for him to get up as we share a room. Chief Engineers on days and Assistant Engineer is on nights.
Got ya. Need more coffee for sure thought you posted CHEF!
Local election day here. Man the comercials are killing me. No back stabbing here though which is surprising.
Im going to be so happy when elections are done for this year. Then all we have to put up with are the ambulance chasers commercials
