I noticed one of the rear number board lights is out. Lionel does not list the LEDs as a replacement part. I'd like to replace it but don't know what LED to use. Need advice. Thanks.

Well, if you post a picture of the lighting board with a clear shot of the LED, we can probably be of better help. Most of those LED's can be replaced. Of course, you'll want to check the wiring as well, it's not always the LED itself.
OK, will do. Thanks.

Easy to fix. Those are bog standard white LED's, I'd replace both so you get matching color temperatures. Hard to tell whether they're 3mm or 5mm, a simple measurement will tell you.
Since you don't have the lead lengths to determine polarity, an easy way is to examine the internal elements. The smaller element is the positive side. Also the flat is normally the negative side.

Ed, They look like 3MM to me.. Get a few of each 3MM, and 5MM... You can always find good use for the extras...
I would test the suspect failed LED using a CR2032 coin cell battery and that could easily be done without even removing the LED from the circuit since the legs are exposed.

As others pointed out- matching the exact color temperature and brightness of the other LEDs might be a challenge, so we are hoping this is a bad solder joint or wire problem VS actually needing to replace the LED.

John, I don't understand your comment "bog" "...Those are bog standard white LED's." Maybe my failure to understand the term is another reason why I had to quit pursuing an EE degree. 
Bog is not a technical term.
Time to look it up:
bog
[ bog, bawg ]
noun
wet, spongy ground with soil composed mainly of decayed vegetable matter. an area or stretch of such ground.
verb (used with or without object), bogged, bog·ging.
to sink in or as if in a bog (often followed by down): We were bogged down by overwork.
Verb Phrases
bog in, Australian Slang. to eat heartily and ravenously.
bog, Generic Slang. ubiquitous. readily encountered most everywhere.

Thanks Mike. So, I need to look in a 'bog' for those LEDs....got it!
It means to be basic, to be ordinary, to be unexceptional, to be uninspired - it just means ordinary. If you say something is 'bog standard', you mean it is perfectly ordinary. "He's got a bog standard car" means a perfectly ordinary car.
Mike needs to expand his search. 
Thanks, John. That's a new one on me and I'm as old or older than you....shows your never too old to learn nor to teach. That's not bog! I think Mike is stuck in the bog!
It must be a Pennsylvania thing, like "it needs cleaned".

Vern you and John were right. Couldn't match the good one, so I replaced both.
Ted, I did just that. Bought a few of them in both sizes.
So, two new "last for life" LEDs installed. Thanks all for the help.

I like John's definition better than mine, which I pulled off the web. I just grabbed the first thing I found that seemed close.

Definitely. I could use a tow truck about now.
