Caption: CN has bought a number of CREX units and they are starting to show up all over the system. Here CN 3922 (ex-CREX 1336) is serving as DP on CN 322; this is at least the third ex-CREX unit to show up east of Toronto. Interestingly enough, the units CN has bought were in the CREX 1300 and 1400-series, not the 1500-series that CN had previously leased and which were set up to be leaders in Canada.
