Trains inbound from ashmont have direction set to '0', which usually means that something is a braintree train. So I was "snapping" them to the braintree route. I've temporarily turned off "snap to path" for subway routes (which don't need it generally) but it would be better to twiddle the direction field for trains coming from ashmont. Right now if you click on an ashmont-originating train it will highlight the braintree branch instead.
