Not really. I have 3 more Gauge 1 steam locomotives operational and a German friend also just gave it a try kzbin.info/www/bejne/el60YamanryaodU

@@wernerje Amazing! I would love to see one in 7" gauge!

Charles Parsons invented a multistage impulse steam turbine. The PRR-S2 model turbine is single stage, but operates on the same principle.

Sorry Emerald, I'm not able to read your encrypted message

Vielen Dank für die Blumen, mir geht es bestens! Aber - wer ist Berlin Berlin TV ?

Thank you for your interest in the subject. I suggest you procure yourself a copy of my turbine book to get more information. www.g1mra.com/books-binders/ The book focusses on precision lost wax casting components ( grabcad.com/library/model-steam-turbine-components-1 ) but shows also earlier, more conventional methods. For the PRR-S2 nozzles, sections of 0.8mm internal dia. medical injection needles were used (silver soldered). Hope this helps.

Why ?

Well, the guy thats me.

Wow I didn't know that you are the guy with a hat I like model trains and trains you know great video

There are two more clips of the PRR-S2 on my chanel. Have a look ! Werner

@@wernerje yes I want thanks

Have a look at my other youtube videos. Then there is www.modelengineeringwebsite.com/Pennsylvania_turbine_loco_1.html plus 2 subsequent contributions. At present I'm working on a little handbook: "The Multipurpose Model Steam Turbine" which will be issued by the Gauge One Model Railway Association (G1MRA). The book will also contain all information on my previous projects.

Oh my god I didn't know you are watching these I like trains too

It does

The torque characteristic of a steam turbine is not very suitable for traction applications. At low rotor speed, efficiency is abysmal. Besides, manpower required to prepare steam engines for duty, run and maintain them is much much higher then for electric or combustion engines. It's money that counts!

1.turbine can only spin in one direction, so the train with one turbine can't move backward. Class S2 installed 2nd smaller turbine just for moving backward,but provide power only 1500hp 2.The turbine has high efficiency ONLY at high RPM,.Since train has shorter traveling distance between each stops than airplan and ship, it spend more time at less efficient low RPM. Of couse there is an alternative way: use turbine drive generator, then power electric motor.However diesel engine is much easier to run.

Have you seen other previous ones? kzbin.info/www/bejne/qHKUoXVsltSbd68 ; kzbin.info/www/bejne/b3LIfWZno6iFqKM

Why ??

@@wernerje it can explode if something goes wrong

Most probably right - go ahead!

I'm going to try one of those commercial turbines as a prime mover (suitably uprated!)

Schau dir das Vorgänger Video an: kzbin.info/www/bejne/iIGke3x6ZqiGnK8

I'm working on the new video. Will be uploaded within a week or so.

Cool!

Thank you for your offre, Joseph. I've got all the Information required. My problem is to figure out where all the piping is going to and up to which detail I`ll be able (and be willing) to model it.For your Meccano project I wish you every success!

You're welcome Werner. Sadly, detailed dimensions for the S2 locomotive are few given the resources available. Even 1947 "Locomotive Cyclopedia" or Railway Mechanical Engineer mostly have detailed dimensions for the turbine units and gear box. Do you have this elevation diagram? prr.railfan.net/diagrams/PRRdiagrams.html?diag=S2.gif&sel=ste&sz=sm&fr=

The Keystone publication, Volume 45, Nr. 3 was supplied with separate, detailed arrangement drawings at its back. If you get a back issue from the PRR Historical Society (or from elsewhere) you`ll have all the informations required.
