Other than Lionel that is.
I thought this would be easy but I have yet to find a source for Leoco 4 pin connectors as used on Lionel's motor driver boards. They appear to be part number 2420S, 2.5mm pitch or just under .100" . I tried the usual suspects including Digikey, Allied, Newark, Mouser. No Luck.
Does another company make an identical one? I prefer to roll my own.

It might be Chuck. I have to make sure they have the pins too. I guess at that price I can take a chance. Thank you for the lead.
Further checking your link is for the 2 position connector which is in stock. They show the 4 pin version as out of stock.
The hunt continues.

So that's the 2420S040000 white 4 ckt.
I believe that is the plug that Electric RR uses in their Cruise M kit...as well as other of their products. I wonder if they bought them all 
. Any possibility that they have a stock?
I think SZH also brings up Leoco connectors. I think it stands for the Suzhou in
Leoco(Suzhou)Precise Industrial Co Ltd
Chuck I checked the Leoco site. The 2024S is the style. The two digits following that is the number of positions. The last digit signifies color, 0 for white, 2 for red. Also the number for the pins, 2453T, is also out of stock.
The Leoco webpage does not list any sales outlets other than direct. I don't need ten thousand pieces.
I have emailed them to try and find out if there are any more distributors. I can get assembled cables from Lionel but at a premium price. I have been able to find virtually all of the other connectors used by Lionel and MTH but this particular one has eluded me. I would prefer not having to jury rig a connector but it could be done using someone elses 2.5mm connector.

John are the JST a direct fit? I looked at those and couldn't tell if they keyed the same.
Pete
I use them for all my upgrades, they are an exact duplicate. I stock all three types in all the sizes, and the matching pins. Whenever I need a connector, I don't have to go scrounging. They're also pretty cheap...
It's impossible to get any reasonable quantity of connectors from Leoco, they seem to sell them by the pallet!
Pete, I have genuine 4-pin LEOCO connectors.
Shoot me a note with how many you need, and we'll go from there.

There's no reason to bend over backwards for the Leoco brand, the JST connectors are form, fit, and function identical.

Todd, I appreciate the offer but after finding a better picture of the JSTs it does look like they are identical. The first pictures I found were pretty blurry. I have an account with Digikey and order from the frequently so I will go that route.
Thank you for all the suggestions.

The reason being, they ARE identical. 
Well, almost. There is a way to tell them apart, the Leoco connectors have pin numbers on the latch side of the shell.

John, do you know what type of JST connector is used on RailSounds boards? Is it the XH style? I have been on the old interweb looking at a lot of pictures posted by varous suppliers, and just can't quite tell if that is the correct style.

Seems like the 2.5 has a ridge on the side and the 2.0 is smooth sided.

Yeah, there must be a small nubbin on the side of each male connector because the female connectors on the board all have a little locking mechanism on the sides.
Initially I thought the connectors were 2.0mm, but after a more careful inspection, the ones on the board above appear to be 2.44mm, so..... 2.5mm or 2.54mm (seems to be a standard)?
Those boards use the JST-EH family of connectors. I don't know how you're measuring, but they're 2.5mm on that board.

I measured across a 4 pin connector from the center of the left pin to the center of the right pin, then divided that answer by 3 to determine pin spacing. Granted, pins could have been "leaning" one way or the other, but it sounds like we're on the same page. Now to find some JST-EH connectors on da bay, with little wires already attached, in mass quantities, at really cheap prices....
Thanks John
As John mentioned above, Digikey is a great souce for the 2.5mm LEOCO-compatible JST-EH connectors.
Lionel Service also has them for sale, albeit at "retail" prices. Just search the following string: 691cn25
Lionel also has the wires with the metal connectors on them -- you'll see them with the same search string above. I'd like to find another source (as Lionel is out of a lot of colors), but haven't had much luck to date.

They're dirt cheap on Digikey, I wouldn't waste your time on eBay. Remember that you have to also have the contacts and the crimping tool, I use the Engineer PA-09 Crimp tool for all the Lionel connectors from 1.5mm to 2.5mm.
You're better off measuring the holes in the mating connector, they don't bend.
