BNSF B23-7s?

According to a board member over at Locophotos.com, BNSF are storing B23-7s at Topeka, KS. Does this mean BNSF is in the process for retiring these ex-ATSF 4 axle GE’s numbered in the #4200 series, which are probably the last Dash7’s in Class I service? And, as we all know, older GE’s don’t last as long with American roads as EMDs.

Railpictures.net, though, shows BNSF B23-7s still in use as late as March of this year, so who knows?

I read on another board that the maintenance agreement with GE on these units expired on March 31st. Sounds like retirement to me on these units.

thats news to me Every time i go to the kansas city train show i see lots of b23-7s bnsf uses them for transfer service and ive seen the sf30b the 4276 several times
