It seems that you missed

in the quoted message.

(situation A) currently there is a railway -> railway should be mapped
(situation B) currently there is a trail and railway -> trail and
railway should be mapped
(situation C) currently there is a trail -> trail should be mapped
(situation D) currently there is neither trail nor railway -> neither
trail nor railway may be mapped

What was situation in the past does not matter.

Ian describes place that changed from situation A to situation C.
Therefore currently only trail is mapped.

The same applies to the second part:

(situation A) currently there is a railway -> railway should be mapped
(situation B) currently there is a railway on embankment -> embankment
and railway should be mapped
(situation C) currently there is a bare* embankment -> embankment should
be mapped (situation D) currently there is neither railway nor
embankment -> neither embankment nor railway may be mapped

What was situation in the past does not matter. We are not mapping
history (who, how and why constructed embankment).

*bare embankment - without rail, railway signals etc.

As I understand this conflict is about whatever embankment itself is
"existing railroad". In my opinion not. 

Though I am not as strongly convinced as on topic whatever completely
demolished railroad (former spur replaced by houses and supermarket) is
mappable.
