They are large enough, BUT don't do it. That could cause some major problems with flow and an accurate glass reading. Most of these glasses are not big enough in diameter to start with and as you run, the water tends to bob up and down especially on grades. Constant attention to the water level works the best here. Air bubbles tend to form in the small glasses used in Gauge-1 locos and the best test of accurate water levels is to check for the bobbing mentioned above.
