Electornics help needed! Lights in coaches with capacitors!

4700uf 35v. It was the biggest they had. I will be doing a run through guide soon, I'm just moulding plastic to hide electronics

That should do the job!.. Will be interesting to see how it goes through turnouts etc with longer loss of power times.

Here's a GIANT capacitor that could be useful for all of you wanting to stop the flicker.

It consists of six, 4.7 Farad , 2.5V caps in series (that's right- farads not microfarads!) to give an overall capacity of 0.78F
NOTE that the volts must not exceed 15V. But you could buy two and put in series and still have 0.4F =400,000uF at up to 30V.
At 15V and 0.8F, you could run a 20mA LED load for 2 minutes and the volts would still only fall to 12V.

Looks like you've got it working successfully to me.
For mine I'm planning on something like Trev's suggestion, 3 x AAA rechargeables, and I may "borrow" the idea I saw on here to use the LEDs out of flickering candles from the pound shop to mimic the effect of oil lamps. Sounds odd I guess but I don't have digital and it means they'll run even when parked.

These are on ebay... http://www.ebay.com.au/itm/3-X-12V-...lway_Models&hash=item2571df6024#ht_500wt_1120

I'm going to get some to use in streetlights to simulate a kero lantern...
Not having Digital sounds fine to me.
