Greetings All;

 

I need some advice on powering a new layout. I am getting back into the hobby after a few decades. The last layout I did was with my father back in the late ’70’s and early ’80’s, so DCC is new to me. 

 

This layout is a ceiling/shelf setup, 402 feet total track length, all Lionel FasTrack. Currently it is divided into 7 power districts. Lionel Legacy control will be used.

 

I would expect that no more than 2 consists (couple locomotives for each) would run at a time with perhaps some switching going on also. Mostly freight with passenger trains added later (including lighted cars). 

 

My question is what to use for track power. My initial thoughts are a Lionel 180 watt PowerHouse for each power district. 

 

The next question is should I insert a Legacy PowerMaster or TMCC Track Power Controller 400 between each powerhouse and the track?

are you going to run any conventional engines?  then add a TPC. 

 

the 180 watt bricks would give you more then enough power. 

The TPC300's would be sufficient. How are you going to handle powering between the blocks? I use block control relays that do power passing, i.e switch the power source in the current block to the power source of the following block when the front wheels of the train hit the following block, and then back to its original source after it clears the block. This way the train is never receiving power from 2 sources at the same time.

Thanks for the reply Don.

 

That is something I have not thought about. Again I'm jumping from early '80's to now, so I am playing a lot of catchup on control systems, wiring, electronics, etc.

 

I am gonna take a guess and say that for that brief period as the train moves from one block to another, getting power from 2 sources, even if the power sources are in phase, could be bad for the electronics in the locomotives? If so I will need to look at that. Any suggestions on where to look for info other than the forum?

That is correct - If there is any voltage difference between the 2 power sources electricity will flow from the higher source to the lower source through the electronics of the train. When I designed my layout I took this into consideration and took steps to ensure that a train is never powered by two power sources. I used boards from 3-rail innovations to do this. They not only do the power passing but also keep the trains 1 block apart and ensure that 2 trains are never powered by the same source. I run 2 trains on a single mainline that is divided into 6 blocks and powered from three sources.  John Kerklo who owned 3-rail innovations stopped selling his boards about a year ago. However, if you are interested I can send you an email with his contact information. I'm pretty sure he has some stock left and the boards are very high quality and built to last.

Hey Chuck and thanks for replying.

For the most part, it’s not a want or need, but mainly ignorance since I haven’t worked a layout since the early 1980’s. So after the plan was done, and going through all the Lionel instructional videos I was overloaded with info. Asked Lionel customer service if the plan, with legacy and 1 powerhouse per power district was on the right track and they said it was. Well, as I am learning, that is A LOT of power.a bit too much.

You could retain the districts and use  switches (either manual or remote controlled) to enable/disable power to a given district.  If you don't need more than 10 amps, I'd stick with 10 amps.  You can always add more if you need them later, especially if you already have stuff blocked out.

Jay,

 

I have 8 power districts in my PRR Panhandle (18.5 x 10, approximately 220' track).  I am using 1 PowerHouse 180 to supply the 4 mainline Power districts and 1 PowerHouse 180 to supply the remaining 4 Power districts (all yards).  I regularly run 2 or more trains on the mainline without problems.  I have a TPC 400 in front of the mainline power districts in case I want to run conventional.

 

Check out the PRR Panhandle division on the Photo Forum.  Photo 4 is a wiring diagram.

I would encourage you to consider a Legacy Power Master before a TPC300 or TPC400.  The Legacy Power Master is due to be available mid year, if you can wait. The Legacy PM has several advantages over the TPC as it relates to protecting the electronics in the newer trains.

 

If you do not require TMCC/Legacy remote control over the power (many cases do not benefit from remote operation); the I suggest the GW-180 - available now.

 

Both the Legacy PM and the GW-180 are current tech, supply 10Amps RMS @ 18VAC, support the quick action protection for the trains, and are solid products.  The TPC is outdated.

There is another topic about the Lionel TMCC Lock On and a TPC. I like the Lock On, but it has always been a problem when using it with the TPC at lower voltages.

 

It sounds like if we use the new Legacy PM when it becomes available, then the TMCC Lock On is going to be superfluous as the Legacy PM is going to provide equal or better protection?

Happy to help.  By the way, the diagram shows the terminal strips for the 4 mainline power districts.  The other 4 district terminal strips live on a separate board on the eastern side of the layout (in case you were wondering).  All are fused and all have indicator lamps (bulbs).
