Please help me!!!
A transformer is used to convert 120 V to 8.6 V in order to power a toy electric train. If there are 260 turns in the primary, how many turns should there be in the secondary?
Best answer:
Answer by jrrymiller The voltage ratio is the same as the turns ratio. So the easiest solution is:
120/8.6 = 260/X whoops I got the X on the bottom, no problem
8.6/120 = X/260 and X = 8.6*260/120
= 18.63 turns
actually you would probably put 19 turns as a practical matter.
a piston charger is charging one or more working cylinders and simultaneously regulating the inlet and outlet aperture leading to no loss of air and fuel in the exhaust.in the main cylinder combustion takes place every turn,lubrication like a four stroke,compact,high torque,power,less fuel consumpt Video Rating: 5 / 5
Question by San EKM: What is the power rating of Diesel engines (WDM2 & 1) and electric engines of trains of Indian Railways?
Do diesel engines employ 2 stroke engines? With forced induction? Pl give details.

Answer by pingraham@sbcglobal.net There’s some information and links on the WDM-2 here:

There’s a lot of good information at the Indian Railways Fan Club site:

In the Table of Contents, go to Locomotives, then Notes on selected classes. You’ll find data and photos there.
If you can find copies of Jane’s World Railways (major libraries may have these), that come out annualy since the late 1940s, you’ll find technical details there for locomotives around the world.
Question by : How does one hook up a power transformer to a Lionel train track?
I inherited a 1949 Lionel train set, which runs from its own transformer. It has no instructions with it. I am unsure how to connect it to get the locomotive running.

Answer by AN-DY You may be best assisted by a local model railway shop, club or exhibition as I am sure some participants would have had some experience with the train set you now have.
Question by Red Jacket: A constant power is supplied to an Electric train?
The following is a question from the Indian Regional Physics Olympiad.
Assume that a constant power P is supplied to an electric train and is fully used in accelerating the train.Obtain relations giving the velocity of the train and distance traveled by it as functions of time.
Please show detailed working.Thanks.
Best answer:
Answer by Dusty_Looks Energy supplied is P* t ( at any time t)
E=Pt=Kinetic energy of train
0.5 m v2= Pt
v2= 2P/m * t
v= k * t^0.5 (k- constant)
dx/dt = k * t^ 0.5
Get x as a function of t.
Rearrange above to get t as function of x and substitute in velocity equation.

The sad saga of the APT-P launch in the early 80s is a well known one, and the sorry state of this surviving power car almost seems appropriate. What most people don’t realise is that although the project was "cancelled" the trains still in use today on both the East and West Coast Mainlines (Pendolino on the WCML and IC225 on the ECML) are derived from the APT-P – indeed the original project name for the ECML IC225 project was APT-U.
In reality, the APT-P project failure was more a failure of management and PR than of the design itself; by the time the six prototype sets were withdrawn they were working without fuss, doing what they were expected to do.
Incidentally the Railway Age museum at Crewe has a partial (6 car – the full train was 14 cars) APT-P rake on display.
Question by steve00878: A step-down transformer is to be used to convert an ac voltage of 105 V to 6 V to power an electric train. If?
A step-down transformer is to be used to convert an ac voltage of 105 V to 6 V to power an electric train. If there are 420 turns in the primary coil, how many turns should there be in the secondary coil?
Best answer:
Answer by jrrymiller The voltage ratio is the same as the turns ratio.
6/105 = X/420
X = 6*420/105 = 24 turns
