Looks like an invisible Cabin, that is broken
there are few alternatives on the DLS:
<kuid:501228:100287> Invisible Cab
<kuid2:544004:100063:2> MM 81-714 cab invisible
<kuid:58223:25414> Marsz-I Invisible Interior Cab
<kuid:648132:101346> Invisible cab no controls
<kuid2:96914:55473:4> Invisible cab
<kuid:648132:101345> Invisible cab hostler controls
<kuid2:439337:101352:1> Invisible cab
<kuid:648132:100800> Invisible cab Full Controls
open the config of the loco/vehicle that needs it
find the line: interior <kuid:58969:1106>
and put 1 of the others
greetings GM
