Mexicano de la Union Locomotives

Hello to all the members of the forum!

I'm from the city of Aguascalientes, Mexico, and I've been investigating a little 11.km line that ran from Rincón de Romos to Tepezalá, the line was called ''Mexicano de la Unión'' and the line had the following engines (probably more)

1: 0-4-0ST H.K. Porter #2209 (july of1900) - Preserved in Morales, SLP (renumbered as 5)
2 :0-4-0ST H.K. Porter #2302 (february of 1902) - Preserved in Morales, SLP (renumbered as 4)
3: 0-4-0ST H.K. Porter #2459 (november of 1901)
4: 0-4-2T H.K. Porter #2992 (february of 1904)
5: 0-4-4T (tipo Forney) H.K. Porter #3006 (february of 1904)
6: 0-6-4 H.K. Porter #3134 (february of 1905)
7: 2-6-0 Baldwin Locomotive Works #37811 (february of 1912)

I wonder if may anyone have any picture or info of any of these locomotives, I would be vary grateful; greetings and thanks!
