Contrast of E2s at Otto-Probst-Platz. On the left is 4324 (with c5 trailer 1504) which was the last of the Bombardier-built batch and has been fitted with LED displays. 4070 and 1470 still have destination and number blinds and were built by SGP at Simmering. I am unable to see any visible difference between the products of the two builders.
