Arnie - fantastic photos, thanks for posting. I loved the Bub electric loco from the 50's and the tunnel with a zeppelin on it.
Just for fun, here is my MUCH NEWER Bub loco and train. Likely from the 60's although I really can't say for sure but his drivers are plastic so that would say at least middle to late 50's probably later.
Here he is with his little train.
Here he shows his "Bub" logo on the front just below the boiler.
To go earlier, here is a Hornby M0 train in its initial livery, about 1930.
Best wishes to all...
Don
