We present results of LWS observations of W28A2, one of
the brightest of the pre-main sequence objects observed by ISO and one
for which we have obtained a very large and thorough set of data.
Full grating scans were made both ON and OFF the source. We also made
follow-up observations using the LWS Fabry-Perot. ON source data
revealed fine structure lines including the
[OI] 63 
m and 145 m lines, whose ratio is anomalous. The FP
results include the OH absorption doublet at 119 m. We will
present models of the region.
