Routing Motor Switches don't detect linked carts at all (and consequently, won't send them down the correct fork of a switch track)… unless the train is LEAD by a Locomotive.

If the Locomotive is at the back of the train, the problem still exists. The detector does NOT detect the train, and route it accordingly.

My Routing Table was simply:
Ridden=False

Thanks so much for doing that, CJ.

Sept 9th commit solves Train with Back-Loco problem and triggering issue when checked against "Ridden" key.

"Type" and "Name" keys do not work (as mentioned by CJ).

Linked carts without Locos do not trigger routing logic, however this is expected, and probably not considered a bug.

I'm sure someone submitted something related to the "Ridden" key recently, but I can't for the life of me find it...

I think @Yopu made a change to the description or something like that.

Definitely not tied to the Ridden key issue. I've also tested it against "Type:minecraft:chest_minecart", and the results are that a single chestcart triggers the switch, but 2 linked chestcarts do not.

I can confirm that this issue exists when Railcraft is the only mod present.

@Forecaster Are you talking about #648 ?

That was the one

The change I made was to the localization. The wrong keyword was being displayed in the help text. Code wasn't touched.
