The NdeM line out of Oriental, Puebla was the last narrow gauge line to operate, and was still intact though dormant last I knew. Just wondering what, if anything is left of the dual gauge yard and engine facilities there, as shown in this 1961 photo. No. 143, sister to the engine pictured, is on display somewhere in Oriental.http://abpr.railfan.net/abprphoto.cgi?j ... deM142.jpg
