I received my DelTang 2.4 RX with integrated ESC today. Holy flippin' smokes is that thing small! It makes a standard postage stamp look big. I saw the photos on the web site but I guess I didn't really visualize it properly. Now, I'm worried about my soldering skills and my eye sight... No worries, I'll just place it under a magnifying lamp and I'll have to get a smaller soldering tip. Might even pop for a good quality soldering station. I've been wanting one for awhile now and now I have an excuse.
<edit> I noticed that he offers the same with some wires attached for train guys. I'd go for that one unless you have the desire to operate it in a different way than just simple powering of a loco. These little things seem to be quite customizable.
David, if for some reason I decided I needed to go up to 7.4v could this little guy handle it?

Smallest tip you can find helps as does the thinnest solder to avoid swamping the pads.
Bernard suggested a version with wires would help people so I now have that available. Happy to swop if you need to.
6v is the 'absolute max' rating of the motor control chip. If you can feed the volts from 2 and 3 AA cells onto your track with all other electronics disconnected you should get an idea of speed range from one lipo.
I don't know what current those would need but the chip used for the ESC is rated by the manufacturer at 500mA. I have a mains controller which is only rated at 450mA. I have receivers with 2 and 3 integrated ESCs which would probably be better for multiple engines.
ON resistance is also important. It is around O.7 ohms. This is identical to the resistance through shorted out test leads on a Fluke multimeter. Yards of wire, track joins and wheel pickups are not going to come anywhere close to that.
David-thanks but ON resistance?? Fluke multimeter? I was just asking a question, I am very happy with my old timey 27MHZ r/c car receiver/ESC's. They have been giving me fine control/performance for over 10 years now. Most all my locos are converted Bachmann On30 locos with Bhueler motors. Wire to the rails? Not me!

I just love being able to have a discussion with a MFG of products I use and know that I'm being listened to... even if you don't end up using my suggestion it at least indicates that there is a strong desire to insure customer satisfaction.
